Chroma signal input.

Input a chroma signal having a burst level

of 300mVp-p via a 0.01µF capacitor.

Normally the S pin signal is input.

This pin is for both ABL control signal

input and VD high-voltage correction

signal input.

130k High-voltage correction has linear control

characteristics when this pin's voltage is in

the approximate range of 1V and 8V.

Control characteristics can be varied

using the EHT_COMP control of the bus.

ABL functions as a PIC/BRT-ABL

(average value type).

The threshold voltage at which ABL

activates can be switched to either 3V or

1V depending on the bus.

CVBS signal/luminance signal input.

Input a 1Vp-p (100% white including sync)

CVBS signal via a 1µF capacitor.

Input the Y signal when a separated Y/C

signal is input.
