General Description

This non-blocking 2x2 crosspoint switch has a fully differential input to output data path for low noise generation and low pulse width distortion. The device can be used as a high speed crosspoint switch, 2:1 multiplexer, 1:2 demultiplexer or 1:2 signal splitter. The inputs can directly interface with LVDS and LVPECL levels.

Features

■ Low jitter, 800 Mbps full differential data path

■ Worst case jitter of 190ps

with PRBS = 223 − 1 data pattern at 800 Mbps

■ Rail-to-rail common mode range is 0.5V to 3.25V
