FUNCTIONAL DESCRIPTION
DIVIDER STAGES
The divider stages provide
-
(R-Y) and
-
(B-Y) reference signals with the correct 90 degrees relation for the demodulators.
PHASE COMPARATOR
The phase comparator compares the
-
(R-Y) reference signal with the burst pulse and controls the frequency and phase
of the reference oscillator.
IDENTIFICATION DEMODULATOR
The identification demodulator delivers a positive going identification signal for PAL-signals at pin 14, also used for the
automatic colour-killer.
SERVICE SWITCH
The service switch has two functions. The first position (V
14-3
<
1 V) allows the adjustment of the reference oscillator.
Therefore the colour is switched on and the burst for the oscillator PLL is switched off. The second position (V
14-3
>
5 V)
switches the colour on and the output signals can be observed.
SANDCASTLE PULSE DETECTOR
Sandcastle pulse detector for burst-gate, line and blanking (horizontal and vertical) pulse detection. The vertical part of
the sandcastle pulse is needed for the internal colour-on and colour-off delay.
PULSE PROCESSING PART
Pulse processing part which shall prevent a premature switching on of the colour. The colour-on delay, two or three field
periods after identification of the PAL signal, is achieved by a counter. The colour is switched off immediately or at the
latest one field period after disappearance of the identification voltage.

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.
