GND = 0V

VH = 3V

VL = 1.5V

RGB OUT

Pins 20, 24 and 28

Adjust the pedestal level

with the BRT pin.

Adjust the contrast

with the PIX and DRV pins.

GND

When a sync signal is added to the RGB input signal, after the signal is sliced into approximately

60mVp-p inside the IC, it is amplified by the gain from the PIX and DRV pins and output.
