Reversible Bridge in a Tiny Package
The PLX Technology PEX 8112 bridge enables designers to migrate legacy PCI bus
interfaces to the new advanced serial PCI Express. This is ideal for including
existing PCI ICs on a PCI Express™ Adapter Board, such as the new ExpressCard™
or AdvancedMC™ standards. The 13mm x 13mm standard BGA package or 10mm
x 10mm fine BGA package offerings makes the PEX 8112 bridge well suited for
applications where board real estate is at a premium. With its low power 0.15 micron
CMOS design, the PEX 8112 consumes only about 400 mW of power.
Forward and Reverse Bridging
The PEX 8112 supports forward and reverse bridging as defined by the
PCI Express-to-PCI/PCI-X Bridge Specification 1.0. 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 8112 not only allows complete configuration of a downstream PCI Express
system from the PCI bus, but it also handles limited PCI Express root functions for
reverse interrupt and Power Management Events.
Block Diagram
The PEX 8112 is equipped with a
standard PCI Express port that
operates as a single, x1 link with a
maximum of 250 Megabytes per
second of throughput per transmit
and receive direction. The single 2.5
Gbps integrated SerDes delivers the
highest bandwidth with the lowest
possible pin count using LVDS
technology.
The PEX 8112 has a single parallel
bus segment supporting the PCI v.3.0
protocol, and a 32-bit wide parallel
data path running up to 66MHz.
The device supports internal queues
with flow control features to optimize
throughput and traffic flow.
