DESCRIPTION

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 voltageon each input in order to haveno dif-

ferential voltage when switching two RGB genera-

tors.

An AC outputsignal higher than 2 Vpp makes gain

goingslowly down to 0dBto protect theTVset video

amplifier from saturation.
