AD8178ABPZ

GENERAL DESCRIPTION

The AD8178 is a high speed, triple 16 × 5 video crosspoint switch matrix. It supports 1600 × 1200 RGB displays at 85 Hz refresh rate, by offering a 450 MHz bandwidth and a slew rate of 1650 V/μs. With −82 dB of crosstalk and −84 dB isolation (at 5 MHz), the AD8178 is useful in many high speed video applications.
