Video switch
Fairchild Semiconductor
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 signals without sync (Chroma, Pb, Pr) at ~1.25V. These DC output levels are for the 6dB gain setting. Higher gain settings increase the DC output levels accordingly. The input clamp / bias mode is selected via I2C.
Unused outputs may be powered down to reduce power dissipation.
