demodulating the chroma.
The oscillation frequency
of VCXO varies depending
on the voltage at this pin.

X’tal
Connect X’tal. In the case
of series capacity, the
oscillation frequency (f
0
)
can be changed. In the
case of parallel capacity,
the changeable range of
frequency can be
changed.

63 control
Outputs the result of
whether the signal is PAL,
SECAM or NTSC.
Connect the output to the
1H DL IC.
In the case of
discrimination between
white or black, the voltage
just before that is retained.
The voltage immediately
after turning-on is not
fixed.
8.4 V: PAL
4.3 V: SECAM
0 V: NTSC
64 V/I output
Outputs R-Y (V) or Q
signal. It includes LPF that
can remove carrier.
The chroma signal that
routed ACC and TOF
circuits (before demo
input) can be monitored by
pulling up this pin at 10
