PIN CONNECTIONS
DE S CRI P T IO N
This integrated circuit provides RGB switching al-
lowing 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 ref-
erence voltage on each input in order to have no dif-
ferential voltage when switching two RGB genera-
tors.
An AC output signal higher than 2 Vpp makes gain
going slowly down to 0dB to protect the TV set video
amplifier from saturation.
Fast blanking output is a logicial OR between FB1
(Pin 8) and FB2 (Pin 10).
