PEX 8111

The PLX Technology PEX 8111 bridge enables designers to migrate legacy PCI bus interfaces to the new advanced serial PCI Express. This is ideal when including existing PCI ICs on a PCI Express™ Adapter Board, such as the new ExpressCard™ standard. This simple bridge can also reside on either end of a PCI Express cable to connect remote functions running the PCI protocol. The PEX 8111 supports forward and reverse bridging. The tiny 10 mm x 10mm Plastic BGA package makes the device bridge ideal for use in applications where board real estate is at a premium. With its low power 0.15 micron CMOS design, the PEX 8111 consumes a maximum power of only 300 mW.

Compliant to the PCI Express-to-PCI/PCI-X Bridge Specification 1.0, the PEX 8111 is capable of operating in either forward or reverse bridging modes. In forward mode, the bridge allows legacy PCI chips and adapters to be used with new PCI Express processor systems. Reverse bridge operation allows conventional PCI processors and chipsets to configure and control advanced PCI Express switches and endpoints. The reverse PEX 8111 not only allows complete configuration of a downstream PCI Express system from the PCI bus, but PEX 8111 also handles limited PCI Express root functions for reverse interrupt and Power Management Events.
