The XIO2001 is a single-function PCI Express to PCI translation bridge that is fully compliant to the PCI Express to PCI/PCI-X Bridge Specification, Revision 1.0. For downstream traffic, the bridge simultaneously supports up to eight posted and four non-posted transactions. For upstream traffic, up to six posted and four non-posted transactions are simultaneously supported.
The PCI Express interface is fully compliant to the PCI Express Base Specification, Revision 2.0.
The PCI Express interface supports a ×1 link operating at full 250 MB/s packet throughput in each direction simultaneously. Also, the bridge supports the advanced error reporting including extended CRC (ECRC) as defined in the PCI Express Base Specification. Supplemental firmware or software is required to fully use both of these features.
