V / I output
Outputs R-Y (V) or I signal.
LPF used to remove carrier is
incorporated.
Chroma signal after passing
through ACC and TOF circuits
(before input to demodulator) can
be monitored by pulling up the pin
at 10 k.
DC
2.5 V

1H DL
control
Outputs the result of signal
identification : PAL, SECAM, or
NTSC. Connect the output to 1H
DL IC.
For B&W identification, the voltage
immediately beforehand is held.
The voltage immediately after
power on is undefined.

X’tal
Connect X’tal. With series
capacitance, oscillation frequency
(f0) can be varied ; with parallel
capacitance, frequency range can
be varied.
