Multistandard Sound Processor Family
Release Note: Revision bars indicate significant
changes to the previous edition. The hardware and
software description in this document is valid for
the MSP 34x5G version B8 and following versions.
1. Introduction
The MSP 34x5G family of single-chip Multistandard
Sound Processors covers the sound processing of all
analog TV standards worldwide, as well as the NICAM
digital sound standards. The full TV sound processing,
starting with analog sound IF signal-in, down to pro-
cessed analog AF-out, is performed in a single chip.
Figure 11 shows a simplified functional block diagram
of the MSP 34x5G.
These TV sound processing ICs include versions for
processing the multichannel television sound (MTS)
signal conforming to the standard recommended by
the Broadcast Television Systems Committee (BTSC).
The DBX noise reduction, or alternatively, Micronas
Noise Reduction (MNR) is performed alignment free.
Other processed standards are the Japanese FM-FM
multiplex standard (EIA-J) and the FM-Stereo-Radio
standard.
Current ICs have to perform adjustment procedures in
order to achieve good stereo separation for BTSC and
EIA-J. The MSP 34x5G has optimum stereo perfor-
mance without any adjustments.
All MSP 34xxG versions are pin compatible to the
MSP 34xxD. Only minor modifications are necessary
to adapt a MSP 34xxD controlling software to the
MSP 34xxG. The MSP 34x5G further simplifies con-
trolling software. Standard selection requires a single
I
2
C transmission only.
Note: The MSP 34x5G version has reduced control
registers and less functional pins. The remaining regis-
ters are software-compatible to the MSP 34x0G. The
pinning is compatible to the MSP 34x0G.
The MSP 34x5G has built-in automatic functions: The
IC is able to detect the actual sound standard automat-
ically (Automatic Standard Detection). Furthermore,
pilot levels and identification signals can be evaluated
internally with subsequent switching between mono/
stereo/bilingual; no I
2
C interaction is necessary (Auto-
matic Sound Selection).
The MSP 34x5G can handle very high FM deviations
even in conjunction with NICAM processing. This is
especially important for the introduction of NICAM in
China.
The ICs are produced in submicron CMOS technology.
The MSP 34x5G is available in the following packages:
PSDIP64, PSDIP52, PMQFP44, PLQFP64, and
PQFP80.

1.3. MSP 34x5G Versions and their Application Fields
Table 11 provides an overview of TV sound standards
that can be processed by the MSP 34x5G family. In
addition, the MSP 34x5G is able to handle the FM-
Radio standard. With the MSP 34x5G, a complete
multimedia receiver covering all TV sound standards
together with terrestrial/cable and satellite radio sound
can be built; even ASTRA Digital Radio can be pro-
cessed (with a DRP 3510A coprocessor).

2.1. Architecture of the MSP 34x5G Family
Fig. 21 on page 8 shows a simplified block diagram of
the IC. The block diagram contains all features of the
MSP 3455G. Other members of the MSP 34x5G family
do not have the complete set of features: The demodu-
lator handles only a subset of the standards presented
in the demodulator block; NICAM processing is only
possible in the MSP 3415G and MSP 3455G (see
dashed block in Fig. 21).
2.2. Sound IF Processing
2.2.1. Analog Sound IF Input
The input pins ANA_IN1+ and ANA_IN
-
offer the pos-
sibility to connect sound IF (SIF) sources to the
MSP 34x5G. The analog-to-digital conversion of the
sound IF signal is done by an A/D-converter. An ana-
log automatic gain circuit (AGC) allows a wide range of
input levels. The high-pass filter formed by the cou-
pling capacitor at pin ANA_IN1+ (see Section 7.
"Appendix D: Application Information" on page 93) is
sufficient in most cases to suppress video compo-
nents. Some combinations of SAW filters and sound IF
mixer ICs, however, show large picture components on
their outputs. In this case, further filtering is recom-
mended.
2.2.2. Demodulator: Standards and Features
The MSP 34x5G is able to demodulate all TV sound
standards worldwide including the digital NICAM sys-
tem. Depending on the MSP 34x5G version, the fol-
lowing demodulation modes can be performed:
A2-Systems: Detection and demodulation of two sep-
arate FM carriers (FM1 and FM2), demodulation and
evaluation of the identification signal of carrier FM2.
NICAM-Systems: Demodulation and decoding of the
NICAM carrier, detection and demodulation of the ana-
log (FM or AM) carrier. For D/K-NICAM, the FM carrier
may have a maximum deviation of 384 kHz.
Very high deviation FM-Mono: Detection and robust
demodulation of one FM carrier with a maximum devi-
ation of 540 kHz.
BTSC-Stereo: Detection and FM demodulation of the
aural carrier resulting in the MTS/MPX signal. Detec-
tion and evaluation of the pilot carrier, AM demodula-
tion of the (L-R)-carrier and detection of the SAP sub-
carrier. Processing of the DBX noise reduction or
Micronas Noise Reduction (MNR).
BTSC-Mono + SAP: Detection and FM demodulation
of the aural carrier resulting in the MTS/MPX signal.
Detection and evaluation of the pilot carrier, detection
and FM demodulation of the SAP-subcarrier. Process-
ing of the DBX noise reduction or Micronas Noise
Reduction (MNR).
Japan Stereo: Detection and FM demodulation of the
aural carrier resulting in the MPX signal. Demodulation
and evaluation of the identification signal and FM
demodulation of the (L-R)-carrier.
FM-Satellite Sound: Demodulation of one or two FM
carriers. Processing of high-deviation mono or narrow
bandwidth mono, stereo, or bilingual satellite sound
according to the ASTRA specification.
FM-Stereo-Radio: Detection and FM demodulation of
the aural carrier resulting in the MPX signal. Detection
and evaluation of the pilot carrier and AM demodula-
tion of the (L-R)-carrier.
The demodulator blocks of all MSP 34x5G versions
have identical user interfaces. Even completely differ-
ent systems like the BTSC and NICAM systems are
controlled the same way. Standards are selected by
means of MSP Standard Codes. Automatic processes
handle standard detection and identification without
controller interaction. The key features of the
MSP 34x5G demodulator blocks are
Standard Selection: The controlling of the demodula-
tor is minimized: All parameters, such as tuning fre-
quencies or filter bandwidth, are adjusted automati-
cally by transmitting one single value to the
STANDARD SELECT register. For all standards, spe-
cific MSP standard codes are defined.
Automatic Standard Detection: If the TV sound stan-
dard is unknown, the MSP 34x5G can automatically
detect the actual standard, switch to that standard, and
respond the actual MSP standard code.
Automatic Carrier Mute: To prevent noise effects or
FM identification problems in the absence of an FM
carrier, the MSP 34x5G offers a configurable carrier
mute feature, which is activated automatically if the TV
sound standard is selected by means of the STAN-
DARD SELECT register. If no FM carrier is detected at
one of the two MSP demodulator channels, the corre-
sponding demodulator output is muted. This is indi-
cated in the STATUS register.

2.2.3. Preprocessing of Demodulator Signals
The NICAM signals must be processed by a deempha-
sis filter and adjusted in level. The analog demodu-
lated signals must be processed by a deemphasis fil-
ter, adjusted in level, and dematrixed. The correct
deemphasis filters are already selected by setting the
standard in the STANDARD SELECT register. The
level adjustment has to be done by means of the FM/
AM and NICAM prescale registers. The necessary
dematrix function depends on the selected sound
standard and the actual broadcasted sound mode
(mono, stereo, or bilingual). It can be manually set by
the FM Matrix Mode register or automatically by the
Automatic Sound Selection.
2.2.4. Automatic Sound Select
In the Automatic Sound Select mode, the dematrix
function is automatically selected based on the identifi-
cation information in the STATUS register. No I
2
C inter-
action is necessary when the broadcasted sound
mode changes (e.g. from mono to stereo).
The demodulator supports the identification check by
switching between mono-compatible standards (stan-
dards that have the same FM-Mono carrier) automati-
cally and non-audible. If B/G-FM or B/G-NICAM is
selected, the MSP will switch between these stan-
dards. The same action is performed for the standards:
D/K1-FM, D/K2-FM, D/K3-FM and D/K-NICAM.
Switching is only done in the absence of any stereo or
bilingual identification. If identification is found, the
MSP keeps the detected standard.
In case of high bit-error rates, the MSP 34x5G auto-
matically falls back from digital NICAM sound to ana-
log FM or AM mono.
Table 21 summarizes all actions that take place when
Automatic Sound Select is switched on.
To provide more flexibility, the Automatic Sound Select
block prepares four different source channels of
demodulated sound (Fig. 22). By choosing one of the
four demodulator channels, the preferred sound mode
can be selected for each of the output channels (loud-
speaker, headphone, etc.). This is done by means of
the Source Select registers.
The following source channels of demodulated sound
are defined:
"FM/AM" channel: Analog mono sound, stereo if
available. In case of NICAM, analog mono only
(FM or AM mono).
"Stereo or A/B" channel: Analog or digital mono
sound, stereo if available. In case of bilingual broad-
cast, it contains both languages A (left) and B
(right).
"Stereo or A" channel: Analog or digital mono
sound, stereo if available. In case of bilingual broad-
cast, it contains language A (on left and right).
"Stereo or B" channel: Analog or digital mono
sound, stereo if available. In case of bilingual broad-
cast, it contains language B (on left and right).
Fig. 22 and Table 22 show the source channel
assignment of the demodulated signals in case of
Automatic Sound Select mode for all sound standards.
Note: The analog primary input channel contains the
signal of the mono FM/AM carrier or the L+R signal of
the MPX carrier. The secondary input channel con-
tains the signal of the 2nd FM carrier, the L-R signal of
the MPX carrier, or the SAP signal.

signals in Automatic Sound Select Mode
2.2.5. Manual Mode
Fig. 23 shows the source channel assignment of
demodulated signals in case of manual mode. If man-
ual mode is required, more information can be found in
Section 6.7. "Demodulator Source Channels in Manual
Mode" on page 91.

S Input Signals
The SCART and I
2
S inputs need only be adjusted in
level by means of the SCART and I
2
S prescale regis-
ters.
2.4. Source Selection and Output Channel Matrix
The Source Selector makes it possible to distribute all
source signals (one of the demodulator source chan-
nels or SCART) to the desired output channels (loud-
speaker, etc.). All input and output signals can be pro-
cessed simultaneously. Each source channel is
identified by a unique source address.
For each output channel, the sound mode can be set
to sound A, sound B, stereo, or mono by means of the
output channel matrix.
If Automatic Sound Select is on, the output channel
matrix can stay fixed to stereo (transparent) for demod-
ulated signals.
2.5. Audio Baseband Processing
2.5.1. Automatic Volume Correction (AVC)
Different sound sources (e.g. terrestrial channels, SAT
channels, or SCART) fairly often do not have the same
volume level. Advertisements during movies usually
have a higher volume level than the movie itself. This
results in annoying volume changes. The AVC solves
this problem by equalizing the volume level.
To prevent clipping, the AVC's gain decreases quickly
in dynamic boost conditions. To suppress oscillation
effects, the gain increases rather slowly for low level
inputs. The decay time is programmable by means of
the AVC register (see page 30).
For input signals ranging from
-
24 dBr to 0 dBr, the
AVC maintains a fixed output level of
-
18 dBr. Fig. 24
shows the AVC output level versus its input level. For
prescale and volume registers set to 0 dB, a level of
0 dBr corresponds to full scale input/output. This is
SCART input/output 0 dBr = 2.0 V
rms
Loudspeaker output 0 dBr = 1.4 V
rms

2.5.2. Loudspeaker Outputs
The following baseband features are implemented in
the loudspeaker output channels: bass/treble, loud-
ness, balance, and volume. A square wave beeper can
be added to the loudspeaker channel.
2.5.3. Quasi-Peak Detector
The quasi-peak readout register can be used to read
out the quasi-peak level of any input source. The fea-
ture is based on following filter time constants:

2.6. SCART Signal Routing
2.6.1. SCART DSP In and SCART Out Select
The SCART DSP Input Select and SCART Output
Select blocks include full matrix switching facilities. To
design a TV set with two pairs of SCART-inputs and
one pair of SCART-outputs, no external switching
hardware is required. The switches are controlled by
the ACB user register (see page 34).
2.6.2. Stand-by Mode
If the MSP 34x5G is switched off by first pulling
STANDBYQ low and then (after >1
s delay) switching
off DVSUP and AVSUP, but keeping AHVSUP
(`Stand-by'-mode), the SCART switches maintain
their position and function. This allows the copying
from selected SCART-inputs to SCART-outputs in the
TV set's stand-by mode.
In case of power on or starting from stand-by (switch-
ing on the DVSUP and AVSUP, RESETQ going high
2 ms later), all internal registers except the ACB regis-
ter (page 34) are reset to the default configuration (see
Table 35 on page 18). The reset position of the ACB
register becomes active after the first I
2
C transmission
into the Baseband Processing part. By transmitting the
ACB register first, the reset state can be redefined.
2.7. I
2
S Bus Interface
The MSP 34x5G has a synchronous master/slave
input/output interface running on 32 kHz.
The interface accepts two formats:
1. I
2
S_WS changes at the word boundary
2. I
2
S_WS changes one I
2
S-clock period before the
word boundaries.
All I
2
S options are set by means of the MODUS and
the I2S_CONFIG registers.
The I
2
S bus interface consists of five pins:
I2S_DA_IN1, I2S_DA_IN2:
I
2
S serial data input: 16, 18....32 bits per sample
I2S_DA_OUT:
I

S serial clock
I2S_WS:
I
2
S word strobe signal defines the left and right
sample
If the MSP 34x5G serves as the master on the I
2
S
interface, the clock and word strobe lines are driven by
the IC. In this mode, only 16 or 32 bits per sample can
be selected. In slave mode, these lines are input to the
IC and the MSP clock is synchronized to 576 times the
I2S_WS rate (32 kHz). NICAM operation is not possi-
ble in slave mode.

2.8. ADR Bus Interface
For the ASTRA Digital Radio System (ADR), the
MSP 3405G, MSP 3415G, and MSP 3455G performs
preprocessing such as carrier selection and filtering.
Via the 3-line ADR-bus, the resulting signals are trans-
ferred to the DRP 3510A coprocessor, where the
source decoding is performed. To be prepared for an
upgrade to ADR with an additional DRP board, the fol-
lowing lines of MSP 34x5G should be provided on a
feature connector:
I2S_DA_IN1 or I2S_DA_IN2
I2S_DA_OUT
I2S_WS
I2S_CL
ADR_CL, ADR_WS, ADR_DA
For more details, please refer to the DRP 3510A data
sheet.
2.9. Digital Control I/O Pins and
Status Change Indication
The static level of the digital input/output pins
D_CTR_I/O_0/1 is switchable between HIGH and
LOW via the I
2
C-bus by means of the ACB register
(see page 34). This enables the controlling of external
hardware switches or other devices via I
2
C-bus.
The digital input/output pins can be set to high imped-
ance by means of the MODUS register (see page 23).
In this mode, the pins can be used as input. The cur-
rent state can be read out of the STATUS register (see
page 25).
Optionally, the pin D_CTR_I/O_1 can be used as an
interrupt request signal to the controller, indicating any
changes in the read register STATUS. This makes poll-
ing unnecessary; I
2
C-bus interactions are reduced to a
minimum (see STATUS register on page 25 and
MODUS register on page 23).
2.10. Clock PLL Oscillator and
Crystal Specifications
The MSP 34x5G derives all internal system clocks
from the 18.432 MHz oscillator. In NICAM or in I
2
S-
Slave mode, the clock is phase-locked to the corre-
sponding source. Therefore, it is not possible to use
NICAM and I
2
S-Slave mode at the same time.
For proper performance, the MSP clock oscillator
requires a 18.432-MHz crystal. Note, that for the
phase-locked mode (NICAM, I
2
S slave), crystals with
tighter tolerance are required.

3. Control Interface
3.1. I
2
C Bus Interface
The MSP 34x5G is controlled via the I
2
C bus slave
interface.
The IC is selected by transmitting one of the
MSP 34x5G device addresses. In order to allow up to
three MSP ICs to be connected to a single bus, an
address select pin (ADR_SEL) has been implemented.
With ADR_SEL pulled to high, low, or left open, the
MSP 34x5G responds to different device addresses. A
device address pair is defined as a write address and a
read address (see Table 31).
Writing is done by sending the write device address,
followed by the subaddress byte, two address bytes,
and two data bytes.
Reading is done by sending the write device address,
followed by the subaddress byte and two address
bytes. Without sending a stop condition, reading of the
addressed data is completed by sending the device
read address and reading two bytes of data.
Refer to Section 3.1.3. for the I
2
C bus protocol and to
Section 3.4. "Programming Tips" on page 37
for pro-
posals of MSP 34x5G I
2
C telegrams. See Table 32
for a list of available subaddresses.
Besides the possibility of hardware reset, the MSP can
also be reset by means of the RESET bit in the CON-
TROL register by the controller via I
2
C bus.
Due to the architecture of the MSP 34x5G, the IC can-
not react immediately to an I
2
C request. The typical
response time is about 0.3 ms. If the MSP cannot
accept another byte of data (e.g. while servicing an
internal interrupt), it holds the clock line I2C_CL low to
force the transmitter into a wait state. The I
2
C Bus
Master must read back the clock line to detect when
the MSP is ready to receive the next I
2
C transmission.
The positions within a transmission where this may
happen are indicated by 'Wait' in Section 3.1.3. The
maximum wait period of the MSP during normal opera-
tion mode is less than 1 ms.
3.1.1. Internal Hardware Error Handling
In case of any hardware problems (e.g. interruption of
the power supply of the MSP), the MSP's wait period is
extended to 1.8 ms. After this time period elapses, the
MSP releases data and clock lines.
Indication and solving the error status:
To indicate the error status, the remaining acknowl-
edge bits of the actual I
2
C-protocol will be left high.
Additionally, bit[14] of CONTROL is set to one. The
MSP can then be reset via the I
2
C bus by transmitting
the RESET condition to CONTROL.
Indication of reset:
Any reset, even caused by an unstable reset line etc.,
is indicated in bit[15] of CONTROL.
A general timing diagram of the I
2
C bus is shown in

C-Controlling
After POWER-ON or RESET (see Fig. 426), the IC is
in an inactive state. All registers are in the Reset posi-
tion (see Table 35 and Table 36), the analog outputs
are muted. The controller has to initialize all registers
for which a non-default setting is necessary.
3.3. MSP 34x5G Programming Interface
3.3.1. User Registers Overview
The MSP 34x5G is controlled by means of user regis-
ters. The complete list of all user registers are given in
Table 35 and Table 36. The registers are partitioned
into the Demodulator section (Subaddress 10
hex
for
writing, 11
hex
for reading) and the Baseband Process-
ing sections (Subaddress 12
hex
for writing, 13
hex
for
reading).
Write and read registers are 16 bit wide, whereby the
MSB is denoted bit[15]. Transmissions via I
2
C bus have
to take place in 16-bit words (two byte transfers, with the
most significant byte transferred first). All write registers,
except the demodulator write registers are readable.
Unused parts of the 16-bit write registers must be zero.
Addresses not given in this table must not be
accessed.
For reasons of software compatibility to the
MSP 34xxD, a Manual/Compatibility Mode is available.
More read and write registers together with a detailed
description can be found in "Appendix B: Manual/Com-
patibility Mode" on page 77.

3.3.2.1. STANDARD SELECT Register
The TV sound standard of the MSP 34x5G demodula-
tor is determined by the STANDARD SELECT register.
There are two ways to use the STANDARD SELECT
register:
Setting up the demodulator for a TV sound standard
by sending the corresponding standard code with a
single I
2
C bus transmission.
Starting the Automatic Standard Detection for ter-
restrial TV standards. This is the most comfortable
way to set up the demodulator (not for MSP 3435G).
Within 0.5 s the detection and setup of the actual TV
sound standard is performed. The detected stan-
dard can be read out of the STANDARD RESULT
register by the control processor. This feature is rec-
ommended for the primary setup of a TV set. Out-
puts should be muted during Automatic Standard
Detection.
The Standard Codes are listed in Table 37.
Selecting a TV sound standard via the STANDARD
SELECT register initializes the demodulator. This
includes: AGC-settings and carrier mute, tuning fre-
quencies, FIR-filter settings, demodulation mode (FM,
AM, NICAM), deemphasis and identification mode.
TV stereo sound standards that are unavailable for a
specific MSP version are processed in analog mono
sound of the standard. In that case, stereo or bilingual
processing will not be possible.
For a complete setup of the TV sound processing from
analog IF input to the source selection, the transmis-
sions as shown in Section 3.5. are necessary.
For reasons of software compatibility to the
MSP 34xxD, a Manual/Compatibility mode is available.
A detailed description of this mode can be found on
page 77.
3.3.2.2. Refresh of STANDARD SELECT Register
A general refresh of the STANDARD SELECT register
is not allowed. However, the following method
enables watching the MSP 34x5G "alive" status and
detection of accidental resets (only versions B6 and
later):
After Power-on, bit[15] of CONTROL will be set; it
must be read once to enable the reset-detection
feature.
Reading of the CONTROL register and checking
the reset indicator bit[15] .
If bit[15] is "0", any refresh of the STANDARD
SELECT register is not allowed.
If bit[15] is "1", indicating a reset, a refresh of the
STANDARD SELECT register and all other MSPG
registers is required.
3.3.2.3. STANDARD RESULT Register
If Automatic Standard Detection is selected in the
STANDARD SELECT register, status and result of the
Automatic Standard Detection process can be read out
of the STANDARD RESULT register. The possible
results are based on the mentioned Standard Code
and are listed in Table 38.
In cases where no sound standard has been detected
(no standard present, too much noise, strong interfer-
ers, etc.) the STANDARD RESULT register contains
00 00
hex
. In that case, the controller has to start further
actions (for example set the standard according to a
preference list or by manual input).
As long as the STANDARD RESULT register contains
a value greater than 07 FF
hex
, the Automatic Standard
Detection is still active. During this period, the MODUS
and STANDARD SELECT register must not be written.
The STATUS register will be updated when the Auto-
matic Standard Detection has finished.
If a present sound standard is unavailable for a specific
MSP-version, it detects and switches to the analog
mono sound of this standard.
Example:
The MSPs 3425G and 3445G will detect a B/G-NICAM
signal as standard 3 and will switch to the analog FM-
Mono sound.

The MSP 34x5G loudspeaker and headphone volume function is divided into a
digital and an analog section. With Fast Mute, volume is reduced to mute posi-
tion by digital volume only. Analog volume is not changed. This reduces any
audible DC plops. To turn volume on again, the volume step that has been used
before Fast Mute was activated must be transmitted.
If the clipping mode is set to "reduce volume", the following rule is used: To
prevent severe clipping effects with bass, treble, or equalizer boosts, the inter-
nal volume is automatically limited to a level where, in combination with either
bass, treble, or equalizer setting, the amplification does not exceed 12 dB.
If the clipping mode is "reduce tone control", the bass or treble value is
reduced if amplification exceeds 12 dB. If the equalizer is switched on, the gain
of those bands is reduced, where amplification together with volume exceeds
12 dB.
If the clipping mode is "compromise", the bass or treble value and volume are
reduced half and half if amplification exceeds 12 dB. If the equalizer is switched
on, the gain of those bands is reduced half and half, where amplification
together with volume exceeds 12 dB.
If the clipping mode is "dynamic", volume is reduced automatically if the signal
amplitudes would exceed
-
2 dBFS within the IC.

Higher resolution is possible: An LSB step in the normal range results in a gain
step of about 1/8 dB, in the extended range about 1/4 dB.
With positive bass settings, internal clipping may occur even with overall volume
less than 0 dB. This will lead to a clipped output signal. Therefore, it is not rec-
ommended to set bass to a value that, in conjunction with volume, would result
in an overall positive gain.

Higher resolution of Loudness Gain is possible: An LSB step results in a gain
step of about 1/4 dB.
Loudness increases the volume of low and high frequency signals, while keep-
ing the amplitude of the reference frequency constant. The intended loudness
has to be set according to the actual volume setting. Because loudness intro-
duces gain, it is not recommended to set loudness to a value that, in conjunction
with volume, would result in an overall positive gain.
The corner frequency for bass amplification can be set to two different values. In
Super Bass mode, the corner frequency is shifted up. The point of constant vol-
ume is shifted from 1 kHz to 2 kHz.

There are several spatial effect modes available:
In Mode A (low byte = 00
hex
), the spatial effect depends on the source mode. If
the incoming signal is mono, Pseudo Stereo Effect is active; for stereo signals,
Pseudo Stereo Effect and Stereo Basewidth Enlargement is effective. The
strength of the effect is controllable by the upper byte. A negative value reduces
the stereo image. A strong spatial effect is recommended for small TV sets
where loudspeaker spacing is rather close. For large screen TV sets, a more
moderate spatial effect is recommended.
In Mode B, only Stereo Basewidth Enlargement is effective. For mono input sig-
nals, the Pseudo Stereo Effect has to be switched on.
It is worth mentioning that all spatial effects affect amplitude and phase
response. With the lower 4 bits, the frequency response can be customized. A
value of 0
hex
yields a flat response for center signals (L = R) but a high-pass
function for L or R only signals. A value of 6
hex
has a flat response for L or R
only signals but a low-pass function for center signals. By using 8
hex
, the fre-
quency response is automatically adapted to the sound material by choosing an
optimal high-pass gain.

3.4. Programming Tips
This section describes the preferred method for initial-
izing the MSP 34x5G. The initialization is grouped into
four sections:
SCART Signal Path (analog signal path)
Demodulator
SCART and I
2
S Inputs
Output Channels
See Fig. 21 on page 8 for a complete signal flow.
SCART Signal Path
1. Select analog input for the SCART baseband pro-
cessing (SCART DSP Input Select) by means of the
ACB register.
2. Select the source for each analog SCART output
(SCART Output Select) by means of the ACB regis-
ter.
Demodulator
For a complete setup of the TV sound processing from
analog IF input to the source selection, the following
steps must be performed:
1. Set MODUS register to the preferred mode and
Sound IF input.
2. Set preferred prescale (FM and NICAM) values.
3. Write STANDARD SELECT register.
4. If Automatic Sound Select is not active:
Choose FM matrix repeatedly according to the
sound mode indicated in the STATUS register.
SCART and I
2
S Inputs
1. Set preferred prescale for SCART.
2. Set preferred prescale for I
2
S inputs
(set to 0 dB after RESET).
Output Channels
1. Select the source channel and matrix for each out-
put channel.
2. Set audio baseband processing.
3. Select volume for each output channel.
3.5. Examples of Minimum Initialization Codes
Initialization of the MSP 34x5G according to these list-
ings reproduces sound of the selected standard on the
loudspeaker output. All numbers are hexadecimal. The
examples have the following structure:
1. Perform an I
2
C controlled reset of the IC.
2. Write MODUS register
(with Automatic Sound Select).
3. Set Source Selection for loudspeaker channel
(with matrix set to STEREO).
4. Set Prescale
(FM and/or NICAM and dummy FM matrix).
5. Write STANDARD SELECT register.
6. Set Volume loudspeaker channel to 0 dB.

3.5.6. Software Flow for Interrupt driven STATUS
Check
A detailed software flow diagram is shown in Fig. 32
on page 39.
If the D_CTR_I/O_1 pin of the MSP 34x5G is con-
nected to an interrupt input pin of the controller, the fol-
lowing interrupt handler can be applied to be automati-
cally called with each status change of the
MSP 34x5G. The interrupt handler may adjust the TV
display according to the new status information.
Interrupt Handler:
<80 11 02 00 <81 dd dd> // Read STATUS

Pin 70, TESTEN Test Enable Pin (Fig. 412)
This pin enables factory test modes. For normal opera-
tion it must be connected to ground.
Pins71, 72, XTAL_IN, XTAL_OUT Crystal Input and
Output Pins (Fig. 420)
These pins are connected to an 18.432 MHz crystal
oscillator which is digitally tuned by integrated shunt
capacitances. An external clock can be fed into
XTAL_IN. The audio clock output signal AUD_CL_OUT
is derived form the oscillator. External capacitors at
each crystal pin to ground (AVSS) are required. It
should be verified by layout, that no supply current for
the digital circuitry is flowing through the ground con-
nection point.
Pin 73, TP Test pin
Pins 74, 75, 76, NC Pins not connected
Pins 77, 78, D_CTR_I/O_1/0 Digital Control Input/
Output Pins (Fig. 419)
General purpose input/output pins. Pin D_CTR_I/O_1
can be used as an interrupt request pin to the control-
ler.
Pin 79, ADR_SEL I
2
C Bus Address Select
(Fig. 416)
By means of this pin, one of 3 device addresses for the
MSP can be selected. The pin can be connected to
ground (I
2
C device addresses 80/81
hex
), to +5V supply
(84/85
hex
) or left open (88/89
hex
).
Pin 80, STANDBYQ Standby
In normal operation, this pin must be high. If the
MSP 34x5G is switched off by first pulling STANDBYQ
low and then (after >1
s delay) switching off DVSUP
and AVSUP, but keeping AHVSUP (`Standby'-mode),
the SCART switches maintain their position and func-
tion.
* Application Note:
All ground pins should be connected to one low-resis-
tive ground plane. All supply pins should be connected
separately with short and low-resistive lines to the
power supply. Decoupling capacitors from DVSUP to
DVSS, AVSUP to AVSS, and AHVSUP to AHVSS are
recommended as closely as possible to these pins.
Decoupling of DVSUP and DVSS is most important.
We recommend using more than one capacitor. By
choosing different values, the frequency range of
active decoupling can be extended. In our application
boards we use: 220 pF, 470 pF, 1.5 nF, and 10
F. The
capacitor with the lowest value should be placed near-
est to the DVSUP and DVSS pins.
The ASG pins should be connected as closely as pos-
sible to the MSP ground. If they are lead with the
SCART-inputs as shielding lines, they should not be
connected to ground at the SCART connector.

1)
External capacitors at each crystal pin to ground are required. They are necessary to tune the open-loop fre-
quency of the internal PLL and to stabilize the frequency in closed-loop operation. Due to different layouts, the
accurate capacitor value should be determined with the customer PCB. The suggested values (1.5...3.3 pF) are
figures based on experience and should serve as "start value".
To adjust the capacitor value, reset the MSP and transfer only the following I
2
C-protocol:
<80 10 00 20 00 60>.
Measure the frequency at pin ADR_CL. Measurement at XTAL_IN/OUT pins is not possible. Change the
capacitor value until the frequency matches 18.432/3 = 6.144 MHz as closely as possible. The higher the
capacity, the lower the resulting clock frequency.
Note: To minimize adjustment tolerances for all MSP-generations, it is strongly recommended to use the so-
called MSP-XTAL-REF ICs (available in all packages) for the capacitor adjustment. Since all MSP-XTAL-REF ICs
do have an AUD_CL_OUT-pin with the 18.432 MHz signal, this pin should be used for the capacitor adjustment
instead of the ADR_CL-pin. After the reset, no I
2
C-protocol should be transmitted. The AUD_CL_OUT-signal is
available at the following pins:

PQFP80
PLQFP64
PMQFP44

2)
For the MSP-XTAL-REF IC, the PMQFP44 pin functionality of the D_CTR_I/O1-pin has been changed to
the Audio_Clock_Out signal. If D_CTR_I/O1 is used in the customer application, this pin must be left open for
the adjustment procedure.

6. Appendix B: Manual/Compatibility Mode
To adapt the modes of the STANDARD SELECT regis-
ter to individual requirements and for reasons of com-
patibility to the MSP 34x5D,
the MSP 34x5G offers
an Manual/Compatibility Mode, which provides sophis-
ticated programming of the MSP 34x5G.
Using the STANDARD SELECT register generally pro-
vides a more economic way to program the
MSP 34x5G and will result in optimal behavior. There-
fore, it is not recommend to use the Manual/Com-
patibility mode.
In those cases, where the
MSP 34x5D is to be substituted by the MSP 34x5G,
the tips given in Section 6.9. on page 91 have to be
obeyed by the controller software.

Description of Demodulator Write Registers
6.3.1. Automatic Switching between NICAM and
Analog Sound
In case of bad NICAM reception or loss of the
NICAM-carrier, the MSP 34x5G offers an Automatic
Switching (fall back) to the analog sound (FM/AM-
mono), without the necessity for the controller of reading
and evaluating any parameters. If a proper NICAM sig-
nal returns, switching back to this source is performed
automatically as well. The feature evaluates the NICAM
ERROR_RATE and switches, if necessary, all output
channels which are assigned to the NICAM-source, to
the analog source, and vice versa.
An appropriate hysteresis algorithm avoids oscillating
effects (see Fig. 61). STATUS[9] and C_AD_BITS[11]
(Addr: 0023 hex) provide information about the actual
NICAM-FM/AM-status.
Fig. 61: Hysteresis for Automatic Switching
6.3.1.1. Function in Automatic Sound Select Mode
The Automatic Sound Select feature (MODUS[0]=1)
includes the procedure mentioned above. By default, the
internal ERROR_RATE threshold is set to 700
dec
. i.e.:
NICAM
analog Sound if ERROR_RATE
>
700
analog Sound
NICAM if ERROR_RATE
<
700/2
The ERROR_RATE value of 700 corresponds to a
BER of approximately 5.46*10
-3
/s.
Individual configuration of the threshold can be done
using Table 65. However, the internal setting used by
the standard selection is recommended.
The optimum NICAM sound can be assigned to the
MSP output channels by selecting one of the "Stereo
or A/B", "Stereo or A", or "Stereo or B" source chan-
nels
6.3.1.2. Function in Manual Mode
If the manual mode (MODUS[0]=0) is required, the
activation and configuration of the Automatic Switching
feature has to be done as described in Table 66.
Note, that the channel matrix of the corresponding out-
put-channels must be set according to the
NICAM-mode and need not to be changed in the FM/
AM-fallback case.

Required threshold = 500: bits[10:1] = 00 1111 1010

For signals above 1.4 Vpp, the minimum gain of 3 dB is switched, and overflow of the A/D converter may result. Due to the
robustness of the internal processing, the IC works up to and even more than 3 Vpp, if norm conditions of FM/NICAM or
FM1/FM2 ratio are supposed. In this overflow case, a loss of FM-S/N-ratio of about 10 dB may appear.

6.3.5. Register MODE_REG
Note: The use of this register is no longer recom-
mended. It should be used only in cases where soft-
ware compatibility to the MSP 34x5D is required.
Using the STANDARD SELECTION register together
with the MODUS register provides a more economic
way to program the MSP 34x5G.
As soon as this register is applied, the MSP 34x5G
works in the MSP 34x5D Manual/Compatibility
Mode
. In this mode, BTSC, EIA-J, and FM-Radio are
disabled
. Only MSP 34x5D features are available; the
use of MODUS and STATUS register is not allowed.
The MSP 34x5G is reset to the normal mode by first
programming the MODUS register, followed by trans-
mitting a valid standard code to the STANDARD
SELECTION register.
The register `MODE_REG' contains the control bits
determining the operation mode of the MSP 34x5G in
the MSP 34x5D Manual/Compatibility Mode; Table 6
12
explains all bit positions.

6.3.6. FIR-Parameter, Registers FIR1 and FIR2
Note: The use of this register is no longer recom-
mended. Use it only in cases where software compati-
bility to the MSP 34x5D is required. Using the STAN-
DARD SELECTION register together with the MODUS
register provides a more economic way to program the
MSP 34x5G.
Data shaping and/or FM/AM bandwidth limitation is
performed by a pair of linear phase Finite Impulse
Response filters (FIR-filter). The filter coefficients are
programmable and either are configured automatically
by the STANDARD SELECT register or written manu-
ally by the control processor via the control bus. Two
not necessarily different sets of coefficients are
required: one for MSP-Ch1 (NICAM or FM2) and one
for MSP-Ch2 (FM1 = FM-mono). In Table 614 several
coefficient sets are proposed.
To load the FIR-filters, the following data values are to
be transferred 8 bits at a time embedded
LSB-bound in a 16-bit word
.
The loading sequences must be obeyed. To change a
coefficient set, the complete block FIR1 or FIR2 must
be transmitted.
Note: For compatibility with MSP 3415B, IMREG1 and
IMREG2 have to be transmitted. The value for
IMREG1 and IMREG2 is 004. Due to the partitioning to
8-bit units, the values 04
hex
, 40
hex
, and 00
hex
arise.
6.3.7. DCO-Registers
Note: The use of this register is no longer recom-
mended. It should be used only in cases where soft-
ware compatibility to the MSP 34x5D is required.
Using the STANDARD SELECTION register together
with the MODUS register provides a more economic
way to program the MSP 34x5G.
When selecting a TV-sound standard by means of the
STANDARD SELECT register, all frequency tuning is
performed automatically.
IF manual setting of the tuning frequency is required, a
set of 24-bit registers determining the mixing frequen-
cies of the quadrature mixers can be written manually
into the IC. In Table 615, some examples of DCO reg-
isters are listed. It is necessary to divide them up into
low part and high part. The formula for the calculation
of the registers for any chosen IF-Frequency is as fol-
lows:
INCR
dec
= int(f/fs
2
24
)
with: int = integer function
f
= IF-frequency in MHz
f
S
= sampling frequency (18.432 MHz)
Conversion of INCR into hex-format and separation of
the 12-bit low and high parts lead to the required regis-
ter values (DCO1_HI or _LO for MSP-Ch1, DCO2_HI
or LO for MSP-Ch2).

6.4. Manual/Compatibility Mode:
Description of Demodulator Read Registers
Note: The use of these register is no longer recom-
mended. It should be used only in cases where soft-
ware compatibility to the MSP 34x5D is required.
Using the STANDARD SELECTION register together
with the STATUS register provides a more economic
way to program the MSP 34x5G and to retrieve infor-
mation from the IC.
All registers except C_AD_BITs are 8 bit wide. They
can be read out of the RAM of the MSP 34x5G if the
MSP 34x5D compatibility mode is required.
All transmissions take place in 16-bit words. The valid
8-bit data are the 8 LSBs of the received data word.
If the Automatic Sound Select feature is not used, the
NICAM or FM-identification parameters must be read
and evaluated by the controller in order to enable
appropriate switching of the channel select matrix of
the baseband processing part. The FM-identification
registers are described in Section 6.6.1.
To handle the
NICAM-sound and to observe the NICAM-quality, at
least the registers C_AD_BITS and ERROR_RATE
must be read and evaluated by the controller. Addi-
tional data bits and CIB bits, if supplied by the NICAM
transmitter, can be obtained by reading the registers
ADD_BITS and CIB_BITS.
6.4.1. NICAM Mode Control/Additional Data Bits
Register
NICAM operation mode control bits and A[2:0] of the
additional data bits.
Format:
Important: "S" = bit[0] indicates correct NICAM-syn-
chronization (S = 1). If S = 0, the MSP 3415/3455G
has not yet synchronized correctly to frame and
sequence, or has lost synchronization. The remaining
read registers are therefore not valid. The MSP mutes
the NICAM output automatically and tries to synchro-
nize again as long as MODE_REG[6] is set.
The operation mode is coded by C4-C1 as shown in
Table 616.
Note: It is no longer necessary to read out and evalu-
ate the C_AD_BITS. All evaluation is performed in the
MSP and indicated in the STATUS register.

6.4.4. NICAM Error Rate Register
Average error rate of the NICAM reception in a time
interval of 182 ms, which should be close to 0. The ini-
tial and maximum value of ERROR_RATE is 2047.
This value is also active if the NICAM bit of
MODE_REG is not set. Since the value is achieved by
filtering, a certain transition time (approx. 0.5 sec) is
unavoidable. Acceptable audio may have error rates
up to a value of 700 int. Individual evaluation of this
value by the controller and an appropriate threshold
may define the fallback mode from NICAM to FM/
AM-mono in case of poor NICAM reception.
The bit error rate per second (BER) can be calculated
by means of the following formula:
BER= ERROR_RATE * 12.3*10

6.4.5. PLL_CAPS Readback Register

6.4.6. AGC_GAIN Readback Register
It is possible to read out the actual setting of
AGC_GAIN in Automatic Gain Mode. In standard
applications, this register is not of interest for the cus-

.
6.4.7. Automatic Search Function for FM-Carrier
Detection in Satellite Mode
The AM demodulation ability of the MSP 3415G and
MSP 3455G offers the possibility to calculate the "field
strength" of the momentarily selected FM carrier,
which can be read out by the controller. In SAT receiv-
ers, this feature can be used to make automatic FM
carrier search possible.
For this, the MSP has to be switched to AM-mode
(MODE_REG[8]), FM-Prescale must be set to
7F
hex
= +127
dec
, and the FM DC notch (see
Section 6.5.7.)
must be switched off. The sound-IF fre-
quency range must now be "scanned" in the
MSP-channel 2 by means of the programmable
quadrature mixer with an appropriate incremental fre-
quency (i.e. 10 kHz). After each incrementation, a field
strength value is available at the quasi-peak detector
output (quasi-peak detector source must be set to
FM), which must be examined for relative maxima by
the controller. This results in either continuing search
or switching the MSP back to FM demodulation mode.
During the search process, the FIR2 must be loaded
with the coefficient set "AUTOSEARCH", which
enables small bandwidth, resulting in appropriate field
strength characteristics. The absolute field strength
value (can be read out of "quasi peak detector output
FM1") also gives information on whether a main FM
carrier or a subcarrier was detected; and as a practical
consequence, the FM bandwidth (FIR1/2) and the
deemphasis (50
s or adaptive) can be switched
accordingly.
Due to the fact that a constant demodulation frequency
offset of a few kHz, leads to a DC level in the demodu-
lated signal, further fine tuning of the found carrier can
be achieved by evaluating the "DC Level Readout
FM1". Therefore, the FM DC Notch must be switched
on, and the demodulator part must be switched back to
FM-demodulation mode.
For a detailed description of the automatic search
function, please refer to the corresponding MSP Win-
dows software.

This table shows more modes for the channel matrix

The sum/difference mode can be used together with
the quasi-peak detector to determine the sound mate-
rial mode. If the difference signal on channel B (right)
is near to zero, and the sum signal on channel A (left)
is high, the incoming audio signal is mono. If there is a
significant level on the difference signal, the incoming

6.5.6. Identification Mode for A2 Stereo Systems
To shorten the response time of the identification algo-
rithm after a program change between two FM-Stereo
capable programs, the reset of the ident-filter can be
applied.
Sequence:
1. Program change
2. Reset ident-filter
3. Set identification mode back to standard B/G or M
4. Wait approx. 500 ms
5. Read stereo detection register
Note: This register is initialized during STANDARD
SELECTION and is automatically updated when Auto-
matic Sound Select (MODUS[0]=1) is on.
6.5.7. FM DC Notch
The DC compensation filter (FM DC Notch) for FM
input can be switched off. This is used to speed up the
automatic search function (see Section 6.4.7.). In nor-
mal FM-mode, the FM DC Notch should be switched
on.
6.6. Manual/Compatibility Mode:
Description of DSP Read Registers
All readable registers are 16-bit wide. Transmissions
via I
2
C bus have to take place in 16-bit words. Some of
the defined 16-bit words are divided into low and high
byte, thus holding two different control entities.
These registers are not writable.
6.6.1. Stereo Detection Register
for A2 Stereo Systems
Note: It is no longer necessary to read out and evalu-
ate the A2 identification level. All evaluation is per-
formed in the MSP and indicated in the STATUS regis-
ter.
6.6.2. DC Level Register
The DC level register measures the DC component of
the incoming FM signals (FM1 and FM2). This can be
used for seek functions in satellite receivers and for IF
FM frequencies fine tuning. A too low demodulation
frequency (DCO) results in a positive DC-Level and
vice versa. For further processing, the DC content of
the demodulated FM signals is suppressed. The time
constant
,
defining the transition time of the DC Level
Register, is approximately 28 ms.

6.7. Demodulator Source Channels in Manual Mode
6.7.1. Terrestric Sound Standards
Table 617 shows the source channel assignment of
the demodulated signals in case of manual mode for
all terrestric sound standards. See Table 22 for the
assignment in the Automatic Sound Select mode. In
manual mode for terrestric sound standards, only two
demodulator sources are defined.
6.7.2. SAT Sound Standards
Table 618 shows the source channel assignment of
the demodulated signals for SAT sound standards.
6.8. Exclusions of Audio Baseband Features
In general, all functions can be switched independently.
Two exceptions exist:
1. NICAM cannot be processed simultaneously with
the FM2 channel.
2. FM adaptive deemphasis cannot be processed
simultaneously with FM-identification.
6.9. Compatibility Restrictions to MSP 34x5D
The MSP 34x5G is fully hardware compatible to the
MSP 34x5D. However, to substitute a MSP 34x5D by
the corresponding MSP 34x5G, the controller software
has to be adapted slightly:
1. The register FM-Matrix (00 0E
hex
low part) must be
changed from "no matrix (00
hex
)" to "sound A mono
(03
hex
)" during mono transmission of all TV-sound
standards (see also Table 617).
2. With the MSP 34x5G, the STANDARD SELECTION
initializes the FM-deemphasis, which is not the case
for the MSP 34x5D. So, if STANDARD SELECTION
is applied, this I
2
C instruction can be omitted.
