PEX 8648
48-Lane, 12-Port PCI Express Gen 2 (5.0 GT/s) Switch, 27 x 27mm FCBGA
The ExpressLane™ PEX 8648 device offers 48 PCI Express Gen 2 (5.0 GT/s) lanes, capable of configuring up to 12 flexible ports. The switch conforms to the PCI Express Base Specification, rev 2.0. The 48-lane switch enables users to add scalable, high bandwidth, non-blocking interconnection to a wide variety of applications including servers, communications, storage, blade servers, and embedded systems. The PEX 8648 boasts the industry's lowest PCIe Gen 2 latency at 140ns and unsurpassed performance with its non-blocking architecture, capable of supporting both host-centric as well as true peer-to-peer traffic. The PEX 8648 also features an on-chip Non-Transparent port for dual-host and failover applications, as well as three on-chip Hot-Plug controllers, allowing users to implement single-chip solutions. The device is hardware configurable and software programmable, allowing users to tailor their port configurations and QoS operating characteristics to suit their application requirements. The PEX 8648 is offered in a 27 x 27mm 676-ball FCBGA. This device is available in lead-free packaging. This device supports Access Control Services (ACS).
