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 IC is useful in many high speed video applications. The AD8177 supports two modes of operation: differential-in to differential-out mode with sync-on CM signaling passed through the switch and differential-in to differential-out mode with CM signaling removed through the switch. The output CM and black level can be conveniently set via external pins. The independent output buffers of the AD8177 can be placed into a high impedance state to create larger arrays by paralleling crosspoint outputs. Inputs can be paralleled as well. The AD8177 offers both serial and parallel programming modes.
