PEX 8114

The ExpressLane PEX 8114 can be used on PCI Expressbased motherboards or embedded systems to connect with legacy PCI or PCI-X slots or devices. In addition, the bridge can be used in add-on cards and mezzanine boards in forward or reverse bridge modes.

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. PEX 8114 supports forward, reverse and non-transparent bridging.

The bridge is equipped with a standard, but flexible PCI PEX 8114 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 PEX 8114 signaling delivers the highest bandwidth with the lowest possible pin count using LVDS technology.

The ExpressLane PEX 8114 has a single parallel bus segment supporting the advanced PCI-X protocol, with a 64-bit wide parallel data path running at 133MHz. The bridge also supports conventional PCI operation.

While both sides of the bridge are evenly matched, the PEX 8114 also supports internal queues with flow control features to optimize throughput and traffic flow.

The small 17mm x 17mm footprint in standard Plastic BGA packaging makes the ExpressLane PEX 8114 ideal for a variety of applications where board real estate is at a premium.
