AD8178:  450 MHz, Triple 16 × 5 Video Crosspoint Switch

Product Details


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.
