GENERAL DESCRIPTION

The AD8117/AD8118 are high speed, 32 × 32 analog crosspoint switch matrices. They offer 600 MHz bandwidth and slew rate of 1800 V/μs for high resolution computer graphics (RGB) signal switching. With less than −70 dB of crosstalk and −80 dB isolation (at 5 MHz), the AD8117/AD8118 are useful in many high speed applications. The 0.1 dB flatness greater than 50 MHz makes the AD8117/AD8118 ideal for composite video switching.
