XIO2001IZGU

Specialized Overview

The XIO2001IZGU 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, eliminating the need for external arbitration hardware. It integrates buffered clocks and adaptive equalization to enhance jitter tolerance and allow for longer PCB traces or cable lengths. This component is designed for high-throughput applications requiring low latency.

Specialized Feature Summary

• Provides a migration path from traditional PCI to PCI Express architecture
• Integrates an internal arbiter supporting up to six downstream PCI bus controllers
• Includes buffered clocks to reduce bill-of-materials costs
• Features built-in adaptive equalization for improved signal integrity

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 IZGU indicates industrial temperature range availability. Confirm package dimensions match the 12mm x 12mm requirement. Ensure compatibility with system voltage levels before integration. Check for updated datasheet revisions regarding electrical characteristics. Validate supply chain authenticity through authorized channels.

Specialized Selection Notes

Select this component when migrating legacy PCI peripherals to PCI Express hosts. Consider the 12mm x 12mm package size for spatial constraints. Evaluate the need for six downstream controller support versus standard four-controller alternatives. Assess if integrated clock buffering meets design requirements to save components. Verify industrial temperature operation needs against commercial variants.

Specialized Part Context

The XIO2001 series serves as a bridge between PCI Express and legacy PCI buses. The IZGU suffix denotes the industrial temperature grade variant within the family. Other variants include ZAJ and ZGU packages for commercial use. This component addresses the growing demand for compact, high-performance interface solutions in mixed-protocol systems.

Specialized Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult official Texas Instruments resources for potential cross-references or newer generations of bridge controllers.
