x1 PCI Express to PCI Bus Translation Bridger
XIO2001
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supportsa×1linkoperatingatfull250MBP/spacket
throughput in each direction simultaneously. Also, the bridge supports advanced
error reporting including extended CRC (ECRC) as defined in the PCI Express base
specification.
