(5V)
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 10kŸ.
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.
Connect X’tal. In the case of series
capacity, the oscillation frequency (f
can be changed. In the case of
parallel capacity, the changeable
range of frequency can be changed.
Connect APC filter demodulating the
chroma. The oscillation frequency of
VCXO varies depending on the
voltage at this pin.
