APPLICATIONS
Cable tuners for TV and VCR (switched concept for
VHF)
Recommended RF bands for the USA:
55.25 to 133.25 MHz, 139.25 to 361.25 MHz and
367.25 to 801.25 MHz.
GENERAL DESCRIPTION
The TDA6402, TDA6402A, TDA6403 and TDA6403A are
programmable 2-band mixers/oscillators and synthesizers
intended for VHF/UHF cable tuners (see Fig.1).
The devices include two double balanced mixers and two
oscillators for the VHF and UHF band respectively, an IF
amplifier and a PLL synthesizer. The VHF band can be
split-up into two sub-bands using a proper oscillator
application and a switchable inductor. Two pins are
available between the mixer output and the IF amplifier
input to enable IF filtering for improved signal handling.
Four PNP ports are provided. Band selection is provided
by using pin PUHF. When PUHF is `ON', the UHF
mixer-oscillator is active and the VHF band is switched off.
When PUHF is `OFF', the VHF mixer-oscillator is active
and the UHF band is `OFF'. PVHFL and PVHFH are used
to select the VHF sub-bands. FMST is a general purpose
port, that can be used to switch an FM sound trap. When
it is used, the sum of the collector currents has to be limited
to 30 mA.
The synthesizer consists of a divide-by-eight prescaler, a
15-bit programmable divider, a crystal oscillator and its
programmable reference divider and a phase/frequency
detector combined with a charge pump which drives the
tuning amplifier, including 33 V output (V33) at pin VT.
Depending on the reference divider ratio (512, 640 or
1024), the phase comparator operates at 7.8125 kHz,
6.25 kHz or 3.90625 kHz with a 4 MHz crystal.

The device can be controlled according to the I
2
C-bus
format or 3-wire bus format depending on the voltage
applied to pin SW (see Table 2). In the 3-wire bus mode
(SW = HIGH), pin LOCK/ADC is the LOCK output.
The LOCK output is LOW when the PLL loop is locked.
In the I
2
C-bus mode (SW = LOW), the lock detector bit FL
is set to logic 1 when the loop is locked and is read on the
SDA line (Status Byte; SB) during a READ operation in
I
2
C-bus mode only. The Analog-to-Digital Converter
(ADC) input is available on pin LOCK/ADC for digital AFC
control in the I
2
C-bus mode only. The ADC code is read
during a READ operation on the I
2
C-bus (see Table 11).
In test mode, pin LOCK/ADC is used as a TEST output for
f
REF
and
1
/
2
f
DIV
, in both I
2
C-bus mode and 3-wire bus mode
(see Table 7).
When the automatic charge pump current switch mode is
activated and when the loop is phase-locked, the charge
pump current value is automatically switched to LOW. This
action is taken to improve the carrier-to-noise ratio.
The status of this feature can be read in the ACPS flag
during a READ operation on the I
2
C-bus (see Table 9).
I
2
C-bus mode (SW = GND)
Five serial bytes (including address byte) are required to
address the device, select the VCO frequency, program
the four ports, set the charge pump current and set the
reference divider ratio. The device has four independent
I
2
C-bus addresses which can be selected by applying a
specific voltage on input CE (see Table 6).
3-wire bus mode (SW = OPEN or VCC)
Data is transmitted to the devices during a HIGH-level on
input CE (enable line). The device is compatible with 18-bit
and 19-bit data formats, as shown in Figs 4 and 5. The first
four bits are used to program the PNP ports and the
remaining bits control the programmable divider. A 27-bit
data format may also be used to set the charge pump
current, the reference divider ratio and for test purposes
(see Fig.6).
It is not allowed to address the devices with words whose
length is different from 18, 19 or 27 bits.
Table 1
Data word length for 3-wire bus
Note
1. The selection of the reference divider is given by an automatic identification of the data word length. When the 27-bit
format is used, the reference divider is controlled by RSA and RSB bits (see Table 8). More details are given in
Chapter "PLL functional description", Section "3-wire bus mode (SW = OPEN or V
CC
)".

PLL FUNCTIONAL DESCRIPTION
The device is controlled via the I
2
C-bus or the 3-wire bus,
depending on the voltage applied on the SW input.
A HIGH-level on the SW input enables the 3-wire bus;
CE/AS, DA and CL inputs are used as enable (CE), data
and clock inputs respectively. A LOW-level on SW input
enables the I
2
C-bus; the CE/AS, DA and CL inputs are
used as address selection (AS), SDA and SCL input
respectively (see Table 2).

Data bytes can be sent to the device after the address
transmission (first byte). Four data bytes are needed to
fully program the device. The bus transceiver has an
auto-increment facility which permits the programming of
the device within one single transmission
(address + 4 data bytes).
The device can also be partially programmed providing
that the first data byte following the address is divider
byte 1 (DB1) or control byte (CB). The bits in the data
bytes are defined in Tables 3 and 4. The first bit of the first
data byte transmitted indicates whether frequency data
(first bit = 0) or control and band-switch data (first bit = 1)
will follow. Until an I
2
C-bus STOP command is sent by the
controller, additional data bytes can be entered without the
need to re-address the device. The frequency register is
loaded after the 8th clock pulse of the second divider byte
(DB2), the control register is loaded after the 8th clock
pulse of the control byte (CB) and the band-switch register
is loaded after the 8th clock pulse of the band switch byte
(BB).

BUS ADDRESS SELECTION
The module address contains programmable address bits
(MA1 and MA0) which offer the possibility of having
several synthesizers (up to 4) in one system by applying a
specific voltage on the CE input. The relationship between
MA1 and MA0 and the input voltage applied to the CE
input is given in Table 6.

Data can be read from the device by setting the R/W bit to
logic 1. After the slave address has been recognized, the
device generates an acknowledge pulse and the first data
byte (status byte) is transferred on the SDA line (MSB
first). Data is valid on the SDA line during a HIGH-level of
the SCL clock signal. A second data byte can be read from
the device if the microcontroller generates an
acknowledge on the SDA line (master acknowledge).
End of transmission will occur if no master acknowledge
occurs. The device will then release the data line to allow
the microcontroller to generate a STOP condition.
The POR flag is set to logic 1 at power-on. The flag is reset
when an end-of-data is detected by the device (end of a
READ sequence). Control of the loop is made possible
with the in-lock flag FL which indicates when the loop is
locked (FL = 1).
The automatic charge pump switch flag (ACPS) is LOW
when the automatic charge pump switch mode is `ON' and
the loop is locked. In other conditions, ACPS = 1.
When ACPS = 0, the charge pump current is forced to the
LOW value.
A built-in ADC is available on LOCK/ADC pin (I
2
C-bus
mode only). This converter can be used to apply AFC
information to the microcontroller from the IF section of the
television. The relationship between the bits A2, A1 and A0
is given in Table 11.

The power-on detection threshold voltage V
POR
is set to
V
CC
= 2 V at room temperature. Below this threshold, the
device is reset to the power-on state.
At power-on state, the charge pump current is set to
280
A, the tuning voltage output is disabled, the test bits
T2, T1 and T0 are set to `001' (automatic charge pump
switch `ON') and RSB is set to logic 1.
PUHF is `OFF', which means that the UHF oscillator and
the UHF mixer are switched off. Consequently, the VHF
oscillator and the VHF mixer are switched on. PVHFL and
PVHFH are `OFF', which means that the VHF tank circuit
is working in the VHF I sub-band. The tuning amplifier is
switched off until the first transmission. In that case, the
tank circuit in VHF I is supplied with the maximum tuning
voltage. The oscillator is therefore working at the end of
the VHF I sub-band.
3-wire bus mode (SW = OPEN or V
CC
)
During a HIGH-level on the CE input (enable line), the data
is clocked into the data register at the HIGH-to-LOW
transition of the clock. The first four bits control the PNP
ports and are loaded into the internal band switch register
on the 5th rising edge of the clock pulse. The frequency
bits are loaded into the frequency register at the
HIGH-to-LOW transition of the chip enable line when an
18-bit or 19-bit data word is transmitted (see Figs 4 and 5).
When a 27-bit data word is transmitted, the frequency bits
are loaded into the frequency register on the 20th rising
edge of the clock pulse and the control bits at the
HIGH-to-LOW transition of the chip enable line (see Fig.6).
In this mode, the reference divider is given by the RSA and
RSB bits (see Table 8). The test bits T2, T1 and T0, the
charge pump bit CP, the ratio select bit RSB and the OS
bit can only be selected or changed with a 27-bit
transmission. They remain programmed if an 18-bit or
19-bit transmission occurs. Only RSA is controlled by the
transmission length when the 18-bit or 19-bit format is
used. When an 18-bit data word is transmitted, the most
significant bit of the divider N14 is internally set to logic 0
and the RSA bit is set to logic 1. When a 19-bit data word
is transmitted, the RSA bit is set to logic 0.
A data word of less than 18 bits will not affect the
frequency register of the device. The definition of the bits
is unchanged compared to I
2
C-bus mode.
It is not allowed to address the devices with words whose
length is different from 18, 19 or 27 bits.

If the first sequence transmitted to the device

If the sequence has 27 bits, the reference divider ratio is
fixed by RSA and RSB bits (see Table 8).

Notes
1. The RF frequency range is defined by the oscillator frequency range and the intermediate frequency (IF).
2. This is the level of the RF signal (100% amplitude modulated with 11.89 kHz) that causes a 750 Hz frequency
deviation on the oscillator signal; it produces sidebands 30 dB below the level of the oscillator signal.
3. Limits are related to the tank circuits used in Fig.19; frequency bands may be adjusted by the choice of external
components.
4. The frequency shift is defined as a change in oscillator frequency when the supply voltage varies from
V
CC
= 5 to 4.75 V (4.5 V) or from V
CC
= 5 to 5.25 V (5.5 V). The oscillator is free running during this measurement.

5. The frequency drift is defined as a change in oscillator frequency when the ambient temperature varies from
T
amb
= 25 to 50
C or from T
amb
= 25 to 0
C. The oscillator is free running during this measurement. The VHF drift
value can be improved by adding a 10 k
resistor between the VHFOSCOC pin and the V
CC
. In that case the typical
VHF drift value can be reduced to 900 kHz.
6. Switch-on drift is defined as the change in oscillator frequency between 5 s and 15 min after switch on. The oscillator
is free running during this measurement.
7. The ripple susceptibility is measured for a 500 kHz ripple at the IF output using the measurement circuit of Fig.19;
the level of the ripple signal is increased until a difference of 53.5 dB occurs between the IF carrier fixed at 100 dB
V
and the sideband components.
8. This is the level of divider interferences close to the IF frequency. For example channel C: f
OSC
= 179 MHz,
1
/
4
f
OSC
= 44.75 MHz. Divider interference is measured with the Philips 37185 demonstration board in accordance
with Fig.19. All ground pins are connected to a single ground plane under the IC. The VHFIN input must be left open
(i.e. not connected to any load or cable); The UHFIN1 and UHFIN2 inputs are connected to a hybrid.
The measured levels of divider interference are influenced by layout, grounding and port decoupling.
The measurement results could vary by as much as 10 dB with respect to the specification.
9. Crystal oscillator interference means the 4 MHz sidebands caused by the crystal oscillator. The rejection has to be
greater than 60 dB for an IF output signal of 100 dB
V.
10. The reference frequency rejection is the level of reference frequency sidebands related to the sound sub-carrier.
The rejection has to be greater than 50 dB for an IF output signal of 100 dB
V.
11. Channel 6 beat is the interfering product of f
RFpix
+ f
RFsnd
-
f
OSC
of channel 6 at 42 MHz.
12. Channel A-5 beat is the interfering product of f
RFpix,
f
IF
and f
OSC
of channel A-4; f
BEAT
= 45.5 MHz. The possible
mechanisms are: f

Tuning amplifier
The tuning amplifier is capable of driving the varicap
voltage without an external transistor. The tuning voltage
output must be connected to an external load of 27 k
which is connected to the tuning voltage supply rail.
The loop filter design depends on the oscillator
characteristics and the selected reference frequency.
Crystal oscillator
The crystal oscillator uses a 4 MHz crystal connected in
series with an 18 pF capacitor thereby operating in the
series resonance mode. Connecting the oscillator to the
supply voltage is preferred, but it can also be connected to
ground.

The reference divider is automatically set to 512 assuming that RSB has been set to logic 1 at power-on. If RSB has been
set to logic 0, in a previous 27-bit sequence, the reference divider will still be set at 640. In that event, the 18-bit sequence
has to be adapted to the 640 divider ratio.
Table 28 19-bit sequence (f
OSC
= 650 MHz; PUHF = ON)
The reference divider is automatically set to 512 assuming that RSB has been set to logic 1 at power-on. If RSB has been
set to logic 0 in a previous 27-bit sequence, the reference divider will still be set at 640. In that event, the 19-bit sequence
has to be adapted to the 640 divider ratio.

SOLDERING
Introduction to soldering surface mount packages
This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our
"Data Handbook IC26; Integrated Circuit Packages"
(document order number 9398 652 90011).
There is no soldering method that is ideal for all surface
mount IC packages. Wave soldering is not always suitable
for surface mount ICs, or for printed-circuit boards with
high population densities. In these situations reflow
soldering is often used.
Reflow soldering
Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
to the printed-circuit board by screen printing, stencilling or
pressure-syringe dispensing before package placement.
Several methods exist for reflowing; for example,
infrared/convection heating in a conveyor type oven.
Throughput times (preheating, soldering and cooling) vary
between 100 and 200 seconds depending on heating
method.
Typical reflow peak temperatures range from
215 to 250
C. The top-surface temperature of the
packages should preferable be kept below 230
C.
Wave soldering
Conventional single wave soldering is not recommended
for surface mount devices (SMDs) or printed-circuit boards
with a high component density, as solder bridging and
non-wetting can present major problems.
To overcome these problems the double-wave soldering
method was specifically developed.
If wave soldering is used the following conditions must be
observed for optimal results:
Use a double-wave soldering method comprising a
turbulent wave with high upward pressure followed by a
smooth laminar wave.
For packages with leads on two sides and a pitch (e):
larger than or equal to 1.27 mm, the footprint
longitudinal axis is preferred to be parallel to the
transport direction of the printed-circuit board;
smaller than 1.27 mm, the footprint longitudinal axis
must be parallel to the transport direction of the
printed-circuit board.
The footprint must incorporate solder thieves at the
downstream end.
For packages with leads on four sides, the footprint must
be placed at a 45
angle to the transport direction of the
printed-circuit board. The footprint must incorporate
solder thieves downstream and at the side corners.
During placement and before soldering, the package must
be fixed with a droplet of adhesive. The adhesive can be
applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the
adhesive is cured.
Typical dwell time is 4 seconds at 250
C.
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
Manual soldering
Fix the component by first soldering two
diagonally-opposite end leads. Use a low voltage (24 V or
less) soldering iron applied to the flat part of the lead.
Contact time must be limited to 10 seconds at up to
300
C.
When using a dedicated tool, all other leads can be
soldered in one operation within 2 to 5 seconds between
270 and 320
C.

Suitability of surface mount IC packages for wave and reflow soldering methods
Notes
1. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum
temperature (with respect to time) and body size of the package, there is a risk that internal or external package
cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the
Drypack information in the
"Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods".
2. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink
(at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version).
3. If wave soldering is considered, then the package must be placed at a 45
angle to the solder wave direction.
The package footprint must incorporate solder thieves downstream and at the side corners.
4. Wave soldering is only suitable for LQFP, TQFP and QFP packages with a pitch (e) equal to or larger than 0.8 mm;
it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.
5. Wave soldering is only suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is
definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
