AD8176: 450 MHz, Triple 16 × 9 Video Crosspoint Switch
The AD8176 is a high speed, triple 16 × 9 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 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 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.
