XIO2200AGGW

Specialized Overview

The XIO2200A is a PCI Express to PCI bus translation bridge manufactured by Texas Instruments. It integrates an IEEE 1394a OHCI controller and a two-port PHY, facilitating the migration from legacy PCI architectures to PCI Express standards. The device supports advanced error reporting, power management features compliant with both PCI and PCI Express specifications, and includes a two-wire serial-bus interface for configuration access. Designed for high-performance data transfer, it provides dedicated hardware arbitration and quality of service mechanisms to manage traffic between the upstream PCI Express link and downstream PCI peripherals.

Specialized Feature Summary

• Integrates an IEEE 1394a OHCI controller alongside the primary bridge functionality
• Supports advanced error reporting and data error forwarding capabilities
• Includes a two-port PHY for physical layer connectivity
• Provides hardware-based PCI port arbitration and virtual channel support

Specialized Applications

• Computer motherboards requiring legacy PCI expansion slots
• Industrial PC control circuit boards
• Measurement and test equipment interfaces
• Security surveillance camera acquisition cards

Specialized Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific ordering suffix matches the required package type and temperature range. Review the datasheet revision history for any updates regarding pin assignments or electrical characteristics prior to finalizing procurement orders.

Specialized Selection Notes

Evaluate system requirements against the integrated 1394a OHCI controller to determine if additional host controllers are necessary. Ensure the design accommodates the specific power-up and power-down sequencing constraints defined in the documentation. Verify compatibility with the target operating system's driver support for the bridge and integrated OHCI functions.
