Description

Clamps and outputs

the DRVOUT (Pin 7)

output signal.

The switch for each

mode is closed and the

clamp potentials

applied to this pin by

selecting CAMVIDEO

(Pin 1) or PBRFC (Pin

2).

Driver VCC.

Camera signal VCC.

Video signal VCC.

2V regulator output

VRB – VRT load:

160Ω or greater.

Be sure to decouple this

pin near the IC pins to

prevent the oscillation

and external noise when

this pin is not used.

(Recommended

capacitor value: 4.7µF)
