General Description

The MAX3640 is a dual-path crosspoint switch for use at OC-12 data rates. The MAX3640 can be used to receive and transmit 622Mbps low-voltage differential signals (LVDS) across a backplane with minimum jitter accumulation. Each path incorporates input buffers, multiplexers, a crosspoint switch, and output drivers. The four output channels have a redundant set of outputs for test or fanning purposes. The device offers signal-path redundancy for critical data streams.
