XIO2001ZAJ

Specialized Overview

The XIO2001ZAJ is a PCI Express to PCI translation bridge manufactured by Texas Instruments. It facilitates the migration from traditional PCI technology to PCI Express. The device operates within a supply voltage range of 3.3 V to 5.25 V and supports a minimum operating temperature of -40°C and a maximum of +85°C. It is housed in a 7 mm x 7 mm ZAJ package, designed for surface mount installation. The component integrates an internal arbiter supporting up to six downstream PCI bus controllers and includes buffered clocks to reduce bill of materials costs.

Specialized Feature Summary

• Integrates an internal arbiter supporting up to six downstream PCI bus controllers, eliminating the need for external arbitration devices.

Specialized Applications

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

Specialized Procurement Notes

Verify the specific suffix ZAJ corresponds to the 7 mm x 7 mm commercial temperature package when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration into production designs.

Specialized Selection Notes

Select this component for applications requiring high bandwidth and low latency during PCI to PCI Express migration. The integrated arbiter simplifies design complexity compared to competitors supporting only four controllers. Ensure system requirements align with the specified commercial temperature range and voltage specifications.

Specialized Part Context

The XIO2001 series serves as a single-function bridge for transitioning legacy PCI systems to PCI Express architectures. It offers industry-leading throughput relative to its physical footprint, allowing designers to maximize performance while minimizing board space consumption in compact electronic systems.

Specialized Replacement Considerations

The XIO2000A is a documented alternative within the same product family offering similar bridge functionality. Verify pinout compatibility and specific feature sets against the XIO2001 before substitution.
