R-Y Output
B-Y Output
Output terminal of demodulated R-Y
or B-Y signal. There is an LPF for
removing carrier built in this pin.
DC
1.9 V
AC
B-Y : 650 mVp-p
R-Y : 510 mVp-p
(with input of PAL-75%
color bar signal)
37 Y1 Output
Output terminal of processed Y
signal. Standard output level : 0.7
Vp-p
38 Fsc VDD
VDD terminal of DDS block. Insert a
decoupling capacitor between this
pin and pin 32 (Fsc GND) at the
shortest distance from both. If
decouping capacitor is inserted at a
distance from the pins, it may cause
spurious deterioration.
39 Black Stretch
To connect filter for controlling black
expansion gain of the black
expansion circuit. Black expansion
gain is determined by voltage of this
pin.
DC
1.6 V
40 16.2 MHz X’tal
To connect 16.2 MHz crystal clock
for generating sub-carrier.Lowest
resonance frequency (f0) of the
crystal oscillation can be varied by
changing DC capacity. Adjust f0 of
the oscillation frequency with the
board pattern.
DC
4.1 V
