Product Summary

The LVCP40 is a 2x2 non-blocking crosspoint switch in a flow-through pin-out allowing for ease in PCB layout. VML signaling is used to achieve a high-speed data throughput while using low power. Each of the output drivers includes a 2:1 multiplexer to allow any input to be routed to any output. Internal signal paths are fully differential to achieve the high signaling speeds while maintaining low signal skews. The applications of the LVCP40 include Clock Buffering/Clock MUXing, Wireless Base Stations, High-Speed Network Routing, Telecom/Datacom, XAUI 802.3ae Protocol Backplane Redundancy.
