colour difference output signals. The
colour-difference output signals are
fed to the TDA4660/TDA4661,
Switched capacitor delay line.

Notes to the characteristics
1. For the SECAM standard, amplitude and H/2 ripple content of the CD signals (R
-
Y) and (B
-
Y) depend on the
characteristics of the external tuned circuit at pins 7 to 10. The resonant frequency of the external tuned circuit must
be adjusted such that the demodulated f
o
voltage level is zero in the
-
(B
-
Y) output channel at pin 3.
Now it is possible to adjust the quality of the external circuit such that the demodulated f
o
voltage level is zero in the
-
(R
-
Y) output channel at pin 1. If necessary, the f
o
voltage level in the
-
(B
-
Y) output channel must be readjusted to
zero by the coil of the tuned circuit.
The external capacitors at the pins 2 and 4 (220 pF each) are matched to the internal resistances of the de-emphasis
network such that every alternate scanned line is blanked.
2. The f
o
frequencies of the 8.8 MHz crystal at pin 21, and the 7.2 MHz crystal at pin 19, can be adjusted when the
voltage at pin 17 is less than 0.5 V (burst OFF), thus providing double subcarrier frequencies of the chrominance
signal.
3. The inquiry sequence for the standard is: PAL
-
SECAM
-
NTSC (3.58 MHz)
-
NTSC (4.43 MHz).
PAL has priority with respect to SECAM, etc.
4. The super sandcastle pulse is compared with three internal threshold levels which are proportional to V
P
.

SOLDERING
Introduction
There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and
surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for
surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often
used.
This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our
"IC Package Databook" (order code 9398 652 90011).
Soldering by dipping or by wave
The maximum permissible temperature of the solder is 260
C; solder at this temperature must not be in contact with the
joint for more than 5 seconds. The total contact time of successive solder waves must not exceed 5 seconds.
The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the
specified maximum storage temperature (T
stg max
). If the printed-circuit board has been pre-heated, forced cooling may
be necessary immediately after soldering to keep the temperature within the permissible limit.
Repairing soldered joints
Apply a low voltage soldering iron (less than 24 V) to the lead(s) of the package, below the seating plane or not more
than 2 mm above it. If the temperature of the soldering iron bit is less than 300
C it may remain in contact for up to
10 seconds. If the bit temperature is between 300 and 400
C, contact may be up to 5 seconds.
