PEX 8647
48-Lane, 3-Port PCI Express Gen 2 (5.0 GT/s) Switch, 27 x 27mm FCBGA
The ExpressLane™ PEX 8647 device offers 48 PCI Express Gen 2 (5.0 GT/s) lanes, configured as 3 x16 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 high-end graphics applications such as high-resolution gaming, high-resolution medical/scientific imaging, and dual-graphics systems. The PEX 8647 boasts the industry's lowest PCIe Gen2 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 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 8647 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).
