GENERAL DESCRIPTION
The AD8175 is a high speed, triple 16 × 9 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 AD8175 is useful in many high speed video applications.
