Flexible, High-Performance Bridge in a Small Package

The PLX Technology ExpressLane™ PEX 8114 is a high performance bridge that enables designers to migrate legacy PCI and PCI-X bus interfaces to the new advanced serial PCI Express™ interface. This flexible device supports forward and reverse transparent bridging.

The bridge is equipped with a standard, but flexible PCI Express port that scales to x1, x2 or x4 lanes with a maximum of 1 Gigabyte per second of throughput per transmit and receive direction. With four 2.5 Gbps integrated SerDes, the standard PCI Express signaling delivers the highest bandwidth with the lowest possible pin count using LVDS technology.
