Design Applications
ExpressCard Adapter – Forward Bridge
The PEX 8111 can be used to quickly upgrade legacy PCI
adapter board designs to be compatible with PCI Express
standard interface slots. In Figure 2, an existing CardBus
IC
is converted for use on an ExpressCard
with the addition of
the single-chip PEX 8111.
Figure 2. Forward Bridge in ExpressCard
Embedded Platform – Reverse Bridge
The PEX 8111 supports Reverse bridging, enabling designers
to utilize the latest PCI Express silicon with widely entrenched
PCI host systems. Reverse bridging allows the host processor
to reside out on the PCI bus; the PEX 8111 will accept
configuration cycles from the PCI side and manage the local
PCI Express interface as a secondary entity within the PCI
software model as in Figure 3.

Standardized PCI Expansion – Forward and
Reverse Bridge Modes
The PEX 8111 is the ideal bridge for facilitating remote I/O
expansion in computing, communications, or data acquisition
applications (see Figure 4). The PCI SIG
PCI Express
cabling specification and the PEX 8111 offer a standards-
based extender for the parallel PCI bus. Because the
PEX 8111 supports reverse bridging operation, the PCI host
system is able to configure the PCI Express link.

Development Tools
PEX 8111 Reference Design Kits
(PEX 8111RDKs) enable
rapid customer design. The Forward Bridge RDK hardware
module includes the PEX 8111 with a single x1 PCI Express
(card-edge) port and single PCI slot on the secondary side.
The Reverse Bridge RDK includes a standard PCI edge
connector (card-edge) and a standard PCI Express slot on the
secondary side. Each PEX 8111RDK can be installed in a
motherboard to test and validate customer software and to
evaluate PEX 8111 features and benefits.
