11.7.1. General description
This integrated circuit provides RGB switching allowing connections between peri TV plug, internal RGB
generator and video processor in a TV set.
The input signal black level is tied to the same reference voltage on each input in order to have no
differential voltage when switching two RGB generators.
An AC output signal higher than 2 Vpp makes gain going slowly down to 0dBto protect the TV set video
amplifier from saturation.
Fast blanking output is a logical OR between FB1 (Pin 8) and FB2 (Pin 10).
