PEX 8680 PCI Gen 2 Express Switches - PEX 8680
The ExpressLane™ PEX 8680 device is the industry's first PCIe switch to offer 80 PCI Express Gen 2 (5.0 GT/s) lanes, capable of configuring up to 20 flexible ports. The switch conforms to the PCI Express Base Specification, rev 2.0. The 80-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 8680 supports the PCI-SIG defined Multicast protocol for PCI Express as well as Multi-root architecture supporting up to six upstream ports. The PEX 8680 also features an on-chip Non-Transparent port for dual-host and failover applications, as well as four 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 8680 is offered in a 35 x 35mm 1156-ball FCBGA. This device is available in lead-free packaging. This device supports Access Control Services (ACS).
