GENERAL DESCRIPTION

The AD8177 is a high speed, triple 16 × 5 video crosspoint switch matrix. It supports 1600 × 1200 RGB displays @ 85 Hz refresh rate by offering a 500 MHz bandwidth and a slew rate of 1800 V/μs. With −88 dB of crosstalk and −94 dB isolation (@ 5 MHz), the AD8177 is useful in many high speed video applications.
