GENERAL DESCRIPTION
The AD8176 is a high speed, triple 16 × 9 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 −83 dB isolation (at
5 MHz), the AD8176 is useful in many high speed video
applications.
The AD8176 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 outputs can be used single-ended in conjunction with
decoded H and V outputs to drive a monitor directly.
The independent output buffers of the AD8176 can be placed
into a high impedance state to create larger arrays by paralleling
crosspoint outputs. Inputs can be paralleled as well. The AD8176
offers both serial and a parallel programming modes.
The AD8176 is packaged in a fully populated 26 × 26 ball
PBGA package and is available over the extended industrial
temperature range of −40°C to +85°C.
