Color difference signal inputs.
Clamped to 5.5V at the burst timing.
GND for the RGB block.
Input which combines YS1SW control with
VM circuit ON/OFF function. Supports
with ternary.
Setting YS1OFF of I
this pin is invalid.
Analog R, G and B signal inputs.
Input a 0.7Vp-p (no sync, 100 IRE) signal
via a capacitor.
The signal is clamped to 5.7V at the burst
timing of the signal input to the HSIN
input (Pin 53).
YM/YS2SW YS2 control input.
When YS2 is high, the RGB2 block signal
is selected; when YS2 is low, the YS1SW
output signal is selected.
YM/YS2 SW YM control input.
When YM is high, the YS1SW output
signal is attenuated by 6dB.
