Toshiba TLP511U RGB Signal Switch Circuit output terminal for SYNC/G, Sync Signal Process Circuit

7HD-4.(CS)RGBand VDSignalsignalsAmplificationare also switchedSectionin the same

way as described above. This IC provides the exclusive

7-4-1. RGB Signal Switch Circuit output terminal for SYNC/G.

The RGB input signals and the video signal demodu- The RGB signals developed enter the RGB amplification lated into RGB signals are switched by QB011 (Analog circuit via buffers, and the HD (CS), VD, SYNC/G signals SW: M52348FP). The block diagram of QB011 is shown enter the sync signal process circuit.
