PEX8747-CA80FBC G

The ExpressLane PEX 8747 is a 48-lane, 5-port, PCIe Gen 3 switch device developed on 40nm technology. The PEX 8747 device offers Multi-Host PCI Express switching capability enabling users to connect a host to its respective endpoints via scalable, high bandwidth, non-blocking interconnection to a variety of graphics applications. The PEX 8747 is optimized to support high-resolution graphics while supporting peer-to-peer traffic and multicast for maximum performance. 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.
