Analog input signal.
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
control register.
Leave these pins open when not
used.
RGB input and YCbCr input can be
selected by the control register.
Clamp period: A clamp current of
±1.2mA (max.) flows.
Signal period: A base current of
0.5µA flows to the IC.
Clamp capacitor connector for
brightness.
Connect 0.1µF ceramic capacitors
between these pins and GND.
Clamp period: A clamp current of
±1.2mA (max.) flows.
Signal period: A base current of
0.5µA flows to the IC.
