DESCRIPTION

· The TEA6425 is designed for switching between video and chroma signals, including CVBS, SVHS, baseband CVBS, and MAC.
· It features 6 video inputs and 8 video outputs, with each input clamp mode, output gain, and switching controlled via the I2C bus.
· The 8 outputs can be individually set to a high impedance state, allowing parallel DC connection of up to 4 devices.

FEATURES

· 6 video inputs and 8 video outputs.
· 2 internal selectable YC adders.
· 15MHz bandwidth at -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 at 5MHz.
· 4 sub-address capability.
· I2C bus control.

APPLICATIONS

· Video signal switching in systems requiring multiple inputs and outputs.
· Integration in video processing systems for CVBS, SVHS, baseband CVBS, and MAC signals.
· Use in applications requiring high impedance output states for parallel device connections.
