Description
R, G and B signal outputs.
The DC level is controlled to
match the SIG.C pin voltage.
Low output in power saving
mode.
VCC2/2V output when preset.
Analog 12.0V power supply.
(for the RGB output circuits)
Analog 12.0V power supply.
(for COM output)
COMMON voltage output.
The output voltage is controlled
by serial communication.
Analog 12.0V GND.
(for COM output)
OSD pulse inputs.
When one of these input pins
exceeds the Vth1 level, all of
the outputs go to black limiter
level; when an input pin
exceeds the Vth2 level, only the
corresponding output goes to
white limiter level.
Analog 3.0V power supply.
H filter input.
Input the video signal via a
capacitor.
