RGB SWITCHINGCIRCUIT
DESCRIPTION
This integrated circuit provides RGB switching al-
lowing connectionsbetween peri TV plug, internal
RGBgeneratorandvideo processorin a TV set.
The input signal blacklevel is tied to the same ref-
erencevoltageon eachinputinordertohavenodif-
ferentialvoltage when switching two RGB genera-
tors.
An AC outputsignal higherthan 2 Vpp makes gain
goingslowly downto 0dBtoprotecttheTVsetvideo
amplifier from saturation.
Fast blanking outputis a logicial OR between FB1
(Pin 8) and FB2 (Pin 10).
