XIO2213BZAJ

Specialized Overview

The XIO2213BZAJ is a single-function PCI Express to PCI local bus translation bridge manufactured by Texas Instruments. The PCI bus interface is internally connected to an IEEE 1394b Open Host Controller Interface (OHCI). This component integrates a three-port PHY for Firewire 800 connectivity, enabling direct PCIe host access to legacy PCI devices and high-speed serial bus peripherals without requiring additional bridge logic.

Specialized Feature Summary

• Integrates PCI Express root complex interface with internal PCI-to-1394b translation
• Includes built-in three-port PHY for IEEE 1394b Firewire 800 connections
• Supports OHCI-compliant host controller functionality for standard driver compatibility

Specialized Applications

• PCIe expansion cards requiring Firewire 800 ports
• Industrial control systems integrating legacy PCI peripherals
• Professional audio interfaces utilizing IEEE 1394b standards

Specialized Procurement Notes

Verify the ZAJ suffix indicates the specific temperature range and package variant required for your design. Confirm RoHS compliance status through official TI documentation before procurement. Ensure ESD protection measures are implemented during handling due to moisture sensitivity classification.

Specialized Selection Notes

Select this component when designing systems requiring native PCIe integration with multiple Firewire 800 endpoints. It eliminates the need for separate bridge controllers, reducing board space and power consumption compared to discrete solutions combining PCIe bridges and 1394b controllers.

Specialized Part Context

This part belongs to Texas Instruments' XIO series of bridge controllers designed for system-on-module and expansion card applications. It addresses the market need for maintaining backward compatibility with PCI and IEEE 1394 devices in modern PCIe-based architectures.

Specialized Replacement Considerations

Public confirmed substitute part numbers are not available in verified documentation. Direct replacement requires matching PCIe-to-PCI bridge specifications and integrated 1394b OHCI functionality from compatible vendors.
