TEA6415C:
16.3.1.
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 I2C-bus.
16.3.2.
Features:
•
20 MHz Bandwidth
•
Cascadable with another TEA6415C (Internal address can be changed by pin 7 voltage)
•
8 inputs (CVBS, RGB, Mac, CHROMA, … )
•
6 Outputs
•
Possibility of MAC or chroma signal for each input by switching-off the clamp with an external resistor
bridge
•
Bus controlled
•
6.5dB gain between any input and output
•
-55dB crosstalk at 5MHz
•
Fully ESD protected
