Pin function

These pins are used to input

external digital signals.

There are two threshold

levels: Vth1 (about 1.0 V) and

Vth2 (about 2.0 V). If one of

I

the RGB signal exceeds Vth1,

then all of the RGB outputs

are set to the black level, and

the output only goes to he

white level when the input

exceeds Vth2.

FBR

Feedback circuit smoothing

capacitor connections. These

circuits are used to control the

DC levels in the RGB and

PCD outputs.

Since these are high-

impedance circuits, capacitors

with low leakage must be

used.
