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
n Bus controlled
n 6.5dB gain between any input and output
n -55dB crosstaljk at 5MHz
n Fully ESD protected
