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.
