Description

External digital signal inputs.

There are two threshold

values: Vth1 (= 1.0V) and

Vth2 (= 2.0V). When one of

the RGB signals exceeds

Vth1, all of the RGB outputs

go to black level; when an

input exceeds Vth2, only the

corresponding output goes to

white level.

Smoothing capacitor

connection for the feedback

circuit of R, G, B and PSIG

output DC level control.

Use a low-leakage capacitor

because of high impedance.

Analog (12V) GND for the PSIG circuit.
