Description

Analog input signal.

I

∗1

Input via a 0.1µF ceramic capacitor.

The typical signal level is 0.7V.

Signals from 0.5V (min.) to

1.0V (max.) can be supported.

IN1 and IN2 are selected by the

I

∗1

control register.

Leave these pins open when not

used.

RGB input and YCbCr input can be
