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™ ICis converted for use on an ExpressCard™ with the addition of the single-chip PEX 8111.

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.
