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.
Connect these pins to GND when not
used.
Analog 3.0V power supply.
In Y/color difference input mode, input
the Y signal to Pin 22, the R-Y signal to
Pin 23 and the B-Y signal to Pin 24.
In RGB input mode, input the G signal
to Pin 22, the R signal to Pin 23 and the
B signal to Pin 24.
Pedestal clamp these pins with external
coupling capacitors.
Sync separation circuit input, or composite
sync/horizontal sync signal input.
During input to the sync separation
circuit, input via a capacitor.
DA output.
Outputs the serial data converted to DC
voltage. The current driving capacity is
±1.0mA (max.).
REF output.
The current driving capacity (sink) is
1.6mA (max.).
