Flexible, High-Performance Bridge in a Small Package
The PLX Technology ExpressLane
enables designers to migrate legacy PCI and PCI-X bus interfaces to the new
advanced serial PCI Express
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.
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 device 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. Leaded and lead-free ROHS versions are available.
Forward and Reverse Bridging
Compliant to the PCI Express-to-PCI/PCI-X Bridge Specification 1.0, the
ExpressLane PEX 8114 is capable of operating in either forward or reverse bridging
modes. In forward mode, the bridge allows legacy PCI or PCI-X chips and adapters
to be used with new PCI Express processor systems. Reverse bridge operation allows
conventional PCI or PCI-X processors and chipsets to configure and control
advanced PCI Express switches and endpoints. The reverse bridge not only allows
complete configuration of a downstream PCI Express system from the PCI/PCI-X
bus, but it also handles limited PCI Express root functions for reverse interrupt and
advanced error handling.
High Performance PCI Express Interface
The fully integrated PCI Express interface incorporates many of the advanced
protocol features in PCI Express such as Automatic Lane Reversal, ECRC, Data
Poisoning, Link State Power Management and Hot Plug. The single link scales from
x4 to x2 or x1 operation through configuration or automatic link training. This
enables the user to reduce power consumption by turning off unused lanes.
