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.

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.
