Muting control

If MUTE (pin 1) is set to HIGH, muting

is carried out simultaneously on all

three channels.

Signal input

Input signals consist of composite

video signals, Y signals, C signals,

RGB, and others. The input level is

within a range of 0 to 1.3 (min.) to 1.5

(typ.).

Signal output

The signal output level is (0.9 + 2

input voltage [V]). Pins 9, 12, and 14

are the pins for sag correction. If pins

10, 13, and 15 are set to 0.2V or less,

the protective circuit is triggered and

the power-saving mode is accessed.
