TEA5114A RGB SWITCHING CIRCUIT .. . .. 25MHz BANDWIDTH CROSSTALK : 55dB SHORT CIRCUIT TO GROUND OR VCC PROTECTED ANTI SATURATION GAIN CHANGING VIDEO SWITCHING DIP16 (Plastic Package) ORDER CODE : TEA5114A PIN CONNECTIONS R1 INPUT 1 16 R OUTPUT GND 2 15 FB R INPUT R 2 INPUT 3 14 V CC G1 INPUT 4 13 G OUTPUT G2 INPUT 5 12 FB G INPUT B 1 INPUT 6 11 B OUTPUT B 2 INPUT 7 10 FB 2 + FB B INPUT FB 1 INPUT 8 9 5114A-01.EPS 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 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).
