XIO2001IZAJ

Specialized Overview

The XIO2001IZAJ is a single-function PCI Express to PCI translation bridge manufactured by Texas Instruments. It facilitates migration from conventional PCI to PCI Express technology while occupying half the board space of comparable solutions. The device supports up to six downstream PCI bus controllers via an internal arbiter and integrates buffered clocks to eliminate external components. It features adaptive equalization for improved jitter tolerance, enabling longer PCB traces or cable lengths. The IZAJ suffix denotes the industrial temperature grade variant housed in a 12 mm x 12 mm ZGU package.

Specialized Feature Summary

• Single-function bridge providing a migration path from conventional PCI to PCI Express technology
• Internal arbiter supporting up to six downstream PCI bus controllers without external hardware
• Integrated buffered clocks reducing bill of materials cost by removing external clock buffers
• Built-in adaptive equalization enhancing jitter tolerance for extended trace or cable lengths

Specialized Applications

• Computer motherboards
• Industrial PC and control circuit boards
• Measurement and test circuit boards
• Security surveillance camera capture cards

Specialized Procurement Notes

Verify the specific suffix IZAJ corresponds to the industrial temperature range and 12x12mm ZGU package as documented in official Texas Instruments datasheets. Confirm that the component meets all environmental specifications required for industrial applications before integration into final designs.

Specialized Selection Notes

Select the XIO2001IZAJ when designing systems requiring high throughput with minimal board space consumption. This variant is appropriate for industrial environments due to its specified temperature rating. Ensure the design leverages the internal arbiter to simplify logic compared to competitors supporting fewer controllers.

Specialized Part Context

The XIO2001 series serves as a bridge between PCI Express and legacy PCI buses. The XIO2001IZAJ specifically represents the industrial-grade version within this family, distinguished by its operating temperature range and ZGU packaging. It complements other bridge solutions by offering higher density and integrated arbitration capabilities.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers include the XIO2000 and XIO2000A from Texas Instruments. These devices also function as PCI Express to PCI bridges but may differ in package options or specific feature sets.
