AD8175:  500 MHz, Triple 16 × 9 Video Crosspoint Switch

Product Description

The AD8175 is a high speed, triple 16 × 9 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 AD8175 is useful in many high speed video applications.

The AD8175 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 AD8175 can be placed into a high impedance state to create larger arrays by paralleling crosspoint outputs. Inputs can be paralleled as well. The AD8175 offers both serial and parallel programming modes.

The AD8175 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.
