SGM6502数据手册SGMICRO中文资料规格书

描述 Description

The SGM6502 is a video switch matrix which features 8 input channels and 6 output channels. The architecture allows any of the 8 inputs to be routed to any of the 6 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 SGM6502 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 SGM6502 is available in a Green TSSOP-24 package. It operates over an ambient temperature range of -40℃ to +85℃.
