TEA6415C:
General 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 connected to several outputs.
All switching possibilities are controlled through the IýC-bus.
Features:
n
20 MHz Bandwith
n
Cascadable with another TEA6415C (Internal address can be changed by pin 7 voltage)
n
8 inputs (CVBS, RGB, Mac, CHROMA, )
n
6 Outputs
n
Possibility of MAC or chroma signal for each input by switching-off the clamp with an external resistor bridge
