Overview
TEA6415C BUS-CONTROLLED VIDEO MATRIX SWITCH s s s s s s s s s 20MHz 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 DIP20 (Plastic Package) ORDER CODE : TEA6415C 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 the switching possibilities are controlled through the I2C bus.

EPS 2 DATA 7 P ROG 4 CLOCK GENERAL DESCRIPTION The main functionof the IC is to switch 8 video input sources on 6 outputs.
Each output can be switched on only one of each input.
On each input an alignment of the lowest level of the signal is made (bottom of synch.
top for CVBS or black level for RGB signals).
Each nominal gain between any input and output is 6.
5dB.
For D2MAC or Chroma signal the alignment is switched off by forcing, with an external resistor bridge, 5 VDC on the input.
Each input can be used as a normal input or as a MAC or Chroma input (with external resistor bridge).
All the switching po...
