Pin description

Muting control

If MUTEA (pin 1) is set to HIGH, the

output is muted. If MUTEB (pin 8) is

set to HIGH, only the chrominance

signal is muted. (The Y signal is

output without being muted.)

Signal input

This is the input pin for chrominance

signals, and is bias-type input. The

input impedance is 20kΩ.

Signal output

These are the Y / C MIX signal output.

Pin 6 is the pin for sag correction. If

pin 7 is set to 0.2V or less, the

protective circuit is triggered and the

power-saving mode is accessed.
