R, G, B and PSIG signal outputs.
The DC level is controlled to match the
SIG.C pin voltage.
Low output in power saving mode.
Analog 12.0V power supply.
R, G, B and PSIG output DC voltage
setting.
Connect a 0.01µF capacitor between
this pin and GND1.
When using a SIG.C of other than
Vcc2/2, input the SIG.C voltage from an
external source.
No connection.
