GENERAL DEscriptION

The SGM6501 is a video switch matrix which features 12 input channels and 9 output channels. The architecture allows any of the 12 inputs to be routed to any of the 9 outputs, and it supports one input to one output or one input to more outputs switching. The routing map is configured by I²C-compatible serial interface.

The SGM6501 has the input clamp function and bias circuitry, the input clamp or bias mode is selectable through I²C interface. Integrated clamp is supported by each input. The function is to set video output sync level to approximately 600mV. If sync signal (Chroma, Pb, Pr) is absent, the input is biased by approximately 1.3V, which is the center of input voltage range.

The SGM6501 is available in Green SSOP-28 and TSSOP-28 packages. It operates over an ambient temperature range of -40℃ to +85℃.
