GENERAL DESCRIPTION The AD8177 is a high speed, triple 16 5 video crosspoint with CM signaling removed through the switch. The output switch matrix. It supports 1600 1200 RGB displays 85 Hz CM and black level can be conveniently set via external pins. refresh rate by offering a 500 MHz bandwidth and a slew rate of The independent output buffers of the AD8177 can be placed 1800 V/s. With 88 dB of crosstalk and 94 dB isolation into a high impedance state to create larger arrays by paralleling ( 5 MHz), the AD8177 is useful in many high speed video crosspoint outputs. Inputs can be paralleled as well. The applications. AD8177 offers both serial and parallel programming modes. The AD8177 supports two modes of operation: differential-in The AD8177 is packaged in a fully populated 26 26 ball to differential-out mode with sync-on CM signaling passed PBGA package and is available over the extended industrial through the switch and differential-in to differential-out mode temperature range of 40C to +85C.
