Design Applications
ExpressCard™ Adapter – Forward Bridge
The PEX 8112 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 8112.
Development Tools
PEX 8112 Reference Design Kits (RDK) enable rapid customer design. The Reverse Bridge RDK (Figure 4) includes a standard
PCI connector (card-edge) and a standard PCI Express slot on the secondary side. The Forward Bridge RDK (Figure 5) includes the
PEX 8112 with a single x1 PCI Express port (card-edge) and four PCI slots on the secondary side. Each PEX 8112RDK can be
installed in a motherboard to evaluate PEX 8112 features and validate customer software.

Embedded Host Platform – Reverse Bridge
The PEX 8112 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 on the PCI bus; the PEX 8112 will accept
configuration cycles from the PCI side and manage the PCI
Express interface as a secondary entity within the PCI
software model as in Figure 3.
