GENERAL DESCRIPTION
The AD8177 is a high speed, triple 16 × 5 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 d B of crosstalk and
- 94 d B isolation (@ 5 MHz), the AD8177 is useful in many high speed video applications. The AD8177 supports two modes...
