Information
The PLX PEX 8112 Fwd Riser is a Reference Design based on the PEX 8112, a single-lane, PCI Express-to-PCI
bridge device. The PEX 8112 Fwd Riser provides a complete hardware platform allowing a PCI device to be
utilized in a PCI Express host system. The PEX 8112 Fwd Riser allows the PEX 8112 bridge device upstream
PCI Express port to be connected to a host system slot by way of a standard PCI Express edge connector (the
PEX 8112 Fwd Riser is designed to plug into a PCI Express motherboard slot). The PEX 8112 Fwd Riser also
allows one PCI adapter to be plugged into the downstream bus, by way of a standard PCI slot residing on the
PEX 8112 Fwd Riser (see
Figure 1
and
Figure 2
below for details).
