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.
The AD8178 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 AD8178 can be placed
into a high impedance state to create larger arrays by paralleling
crosspoint outputs. Inputs can be paralleled as well. The AD8178
offers both serial and a parallel programming modes.
The AD8178 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.
