GENERAL DESCRIPTION
The AD8178 is a high speed, triple 16 × 5 video crosspoint switch matrix. It supports 1600 × 1200 RGB displays @ 85 Hz refresh rate, by offering a 450 MHz bandwidth and a slew rate of 1650 V/μs. With −82 dB of crosstalk and −90 dB isolation (@ 5 MHz), the AD8178 is useful in many high speed video applications.

FEATURES
