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 PEX 8111 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.
Forward and Reverse Bridging
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 it also handles limited
PCI Express
root functions
for reverse interrupt and Power Management Events.
Block Diagram
The PEX 8111 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. With a
single 2.5 Gbps integrated SerDes, the
standard PCI Express signaling delivers
the highest bandwidth with the lowest
possible pin count using LVDS
technology.
The PEX 8111 has a single parallel bus
segment supporting the PCI v 3.0
protocol. With a 32-bit wide parallel data
path running at 33MHz, the PCI
bandwidth is 132 Megabytes per second.
While the PCI Express link
accommodates the full PCI bus
bandwidth, the device also supports
internal queues with flow control features
to optimize throughput and traffic flow.
