Description

The XIO2000 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 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 a x1 link operating at full 250 MB/s packet throughput in each direction simultaneously. Two independent VCs are supported. The second VC is optimized for isochronous traffic types and quality-of-service (QoS) applications. Also, the bridge supports the advanced error reporting capability including extended CRC (ECRC) as defined in the PCI Express Base Specification. Supplemental firmware or software is required to fully utilize both of these features.

Robust pipeline architecture is implemented to minimize system latency across the bridge. If parity errors are detected, then packet poisoning is supported for both upstream and downstream operations.

The PCI local bus is fully compliant with the PCI Local Bus Specification (Revision 2.3) and associated programming model. Also, the bridge supports the standard PCI-to-PCI bridge programming model.

The PCI bus interface is 32-bit and can operate at either 33 MHz or 66 MHz. Also, the PCI interface provides fair arbitration and buffered clock outputs for up to 6 subordinate devices. The bridge has advanced VC arbitration and PCI port arbitration features for upstream traffic. When these arbitration features are fully utilized, bridge throughput performance may be tuned for a variety of complex applications.

Power management (PM) features include active state link PM, PME mechanisms, the beacon and wake protocols, and all conventional PCI D-states. If the active state link PM is enabled, then the link automatically saves power when idle using the L0s and L1 states. PM active state NAK, PM PME, and PME-to-ACK messages are supported. Standard PCI bus power management features provide several low power modes, which enable the host system to further reduce power consumption.

The bridge has additional capabilities including, but not limited to, serial IRQ with MSI messages, serial EEPROM, power override, clock run, and PCI bus LOCK\. Also, eight general-purpose inputs and outputs (GPIOs) are provided for further system control and customization.
