PCI Express to PCI bus translation bridge

3 May 2006 DSP, Micros & Memory

The XIO2000A is a single-function PCI Express to PCI bus translation bridge from Texas Instruments in a 201BGA Microstar package. For downstream traffic, the bridge simultaneously supports up to eight posted and four nonposted transactions for each enabled virtual channel (VC). For upstream traffic, up to six posted and four nonposted transactions are simultaneously supported for each VC. The PCI Express interface is fully compliant to the PCI Express Base Specification, Revision 1.0a.

The PCI Express interface supports an X1 link operating at full 250 MBps packet throughput in each direction simultaneously. Two independent VCs are supported. The second VC is optimised for isochronous traffic types and quality-of-service (QoS) applications.

The PCI bus interface is 32-bit and can operate at either 33 MHz or 66 MHz. Power management (PM) features include active state link PM, PME mechanisms, the beacon and wake protocols, and all conventional PCI D-states.
