TEA6415CD

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.
