TEA6415C
BUS-CONTROLLED VIDEO MATRIX SWITCH
s 20MHz BANDWIDTH
s CASCADABLE WITH ANOTHER TEA6415C
(INTERNAL ADDRESS CAN BE CHANGED BY
PIN 7 VOLTAGE)
s 8 INPUTS (CVBS, RGB, MAC, CHROMA, ...)
s 6 OUTPUTS
s POSSIBILITY OF MAC OR CHROMA SIGNAL
FOR EACH INPUT BY SWITCHING-OFF THE
CLAMP WITH AN EXTERNAL RESISTOR
BRIDGE
s BUS CONTROLLED
s 6.5dB GAIN BETWEEN ANY INPUT AND OUT-
PUT
s -55dB CROSSTALK AT 5MHz
s FULLY ESD PROTECTED
DESCRIPTION
The main function of the TEA6415C is to switch 8
video input sources on the 6 outputs.
Each output can be switched to only one of the
inputs whereas but any same input may be con-
nected to several outputs.
All the switching possibilities are controlled through
the I2C bus.
