PEX8114-AA13BI

PCI Express to PCI Bridge

Unspecified 

Board and System Design Applications

The ExpressLane PEX 8114 can be used on PCI Express-

based motherboards or embedded systems to connect with

legacy PCI or PCI-X slots or devices. In addition, the bridge

can be used in add-on cards and mezzanine boards in forward

or reverse bridge modes.

Motherboards

The simple design and small footprint of the ExpressLane

PEX 8114 make it an ideal bridge solution for the

motherboard (see Figure 1), providing for PCI or PCI-X slot

connectivity and for interface to legacy native PCI or PCI-X

silicon I/O components on the motherboard.

Adapter Boards-Forward Bridge

In Forward Transparent Mode (see Figure 3), the

ExpressLane PEX 8114 can be used to quickly upgrade legacy

PCI or PCI-X adapter board designs to be compatible with

PCI Express standard interface slots.

In Forward Non-Transparent Mode (see Figure 4), the

ExpressLane PEX 8114 will enable intelligent subsystems on

the PCI bus to manage local configuration without

interference from the host processor on the PCI Express side.

In addition, the ExpressLane PEX 8114 is ideal for enabling

PCI Express slot connectivity on motherboards with existing

PCI or PCI-X chipsets (see Figure 2). The reverse bridge

function including reverse bridge root registers means

customers can upgrade existing designs without changing their

choice of CPU chipset.
