TEA6425D
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). PIN CONNECTIONS
