64-Lane, 16-Port PCI Express Gen 3 (8 GT/s) Switch, 35 x 35mm FCBGA

The ExpressLane™ PEX8764 is a 64-lane, 16-port, PCIe Gen3 switch device developed on 40nm technology. PEX8764 offers Multi-Host PCI Express switching capability that enables users to connect multiple hosts to their respective endpoints via scalable, high-bandwidth, non-blocking interconnection to a wide variety of applications including servers, storage, communications, and graphics platforms. In addition to high number lane/port count, the device offers two NT ports and clock isolation capability. Due to their backwards compatibility, designing with PCIe Gen3 switches in mixed (Gen1, Gen2 and Gen3) systems allows designers to future-proof their designs for full Gen3 enablement when migrating to next-generation end-points. The PEX8764 is well suited for fan-out, aggregation, and peer-to-peer traffic patterns. Included is PLX's proprietary visionPAK debug software, which allows, for example, internal receive-eye observation after equalization and access to the devices' internal debug registers thus enabling faster time to market.
