供应视频切换矩阵电路

"视频切换矩阵电路 
The XZD6502 provides eight inputs that can be routed to any of six outputs. Each input can be routed to one or more outputs, but only one input may be routed to any output.Each input supports an integrated clamp option to set the output sync tip level of video
with sync to ~300mV. Alternatively, the input may be internally biased to center output **s without sync (Chroma, Pb, Pr) at ~1.25V.All outputs are designed to drive a 150Ω DC-coupled load. Each output can be programmed to provide either 0dB or 6dB of ** gain.Input-to-output routing and input bias mode functions are controlled via an I2C-compatible digital interface."
