Description
Composite video signal input.
Clamped to approximately 3.1V.
Input the input signal through
capacitor. Connect protective
resistor of 220Ω between this pin
and the capacitor.
The composite video signal input
to CV1 is also taken into the
"SYNC DETECT circuit" of which
SYNC is existed or not.
