TEA6425 VIDEO CELLULAR MATRIX . . . . . . . . . 6 VIDEO INPUTS - 8 VIDEO OUTPUTS 2 INTERNAL SELECTABLE YC ADDERS 15MHz BANDWIDTH @ -3dB SELECTABLE 0.5/6.5dB GAIN FOR EACH OUTPUT HIGH IMPEDANCE SWITCH FOR EACH OUTPUT (3-state operation) PROGRAMMABLE CLAMP MODE ON EACH INPUT (sync bottom or average value) -60dB CROSSTALK @ 5MHz 4 SUB-ADDRESS CAPABILITY I2C BUS CONTROL DIP20 (Plastic Package) ORDER CODE : TEA6425 DESCRIPTION This device is intended for switching between video and chroma signals such as CVBS, SVHS, baseband CVBS, MAC. Each input clamp mode, each output gain, all switching are controlled through the I2C bus. The 8 outputscan be set separatelyin high impedance state, to enable parallel DC connection of several devices (up to 4).
