Clamp input

Input composite video or the Y signal separated from Y / C.

Biased input

Input the chroma signal. Terminated with a 20k

Ω resistor.

Power supply

Biased output

Output for the signal input to IN3. When connected to earth a protection circuit operates,

and the IC enters power-save mode.

Clamped output

Output for the signal input to IN2. When connected to earth a protection circuit operates,

and the IC enters power-save mode.
