TEA5114A single integrated circuit Integrated Circuit Chip RGB SWITCHING CIRCUIT
TEA5114A
RGB SWITCHING CIRCUIT
. 25MHz BANDWIDTH
. CROSSTALK : 55dB
. SHORT CIRCUIT TO GROUND OR VCC PROTECTED
. ANTI SATURATION GAIN CHANGING
. VIDEO SWITCHING
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 voltageon each input in order to haveno differential voltage when switching two RGB generators.
An AC output signal higher than 2 Vpp makes gain goingslowly down to 0dBto protect the TV set video amplifier from saturation.
Fast blanking output is a logicial OR between FB1 (Pin 8) and FB2 (Pin 10).
