XIO2001ZGU

Specialized Overview

The XIO2001ZGU is a PCI Express to PCI bus translation bridge manufactured by Texas Instruments. It operates within the commercial temperature range and utilizes a 12 mm x 12 mm ZGU package. The device facilitates migration from traditional PCI architectures to PCI Express technology, offering high throughput capabilities relative to its footprint. Key electrical characteristics include support for multiple downstream PCI bus controllers via an internal arbiter and integrated buffering for clock signals.

Specialized Feature Summary

• Provides a compact solution for migrating legacy PCI designs to PCI Express standards
• Integrates an internal arbiter supporting up to six downstream PCI bus controllers without external components
• Includes buffered clock circuitry to eliminate the need for external clock buffers

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 ZGU corresponds to the 12x12mm package and commercial temperature rating. Confirm availability through authorized TI distributors or direct channels. Ensure ordering documentation matches the exact part number to avoid confusion with industrial variants like IZGU.

Specialized Selection Notes

Select this component when board space constraints require a small form factor bridge. Consider it for applications needing support for multiple downstream PCI controllers without external arbitration logic. Evaluate the need for integrated clock buffering to reduce bill of materials complexity.

Specialized Part Context

This part belongs to the XIO series of interface bridges designed by Texas Instruments. It serves as a single-function bridge specifically for translating between PCI Express and legacy PCI buses. The ZGU suffix denotes the specific plastic quad flat no-lead package variant suitable for commercial applications.

Specialized Replacement Considerations

The XIO2000A is a documented related bridge component from Texas Instruments. Verify pinout compatibility and feature parity before substitution. Cross-reference datasheets to ensure performance requirements are met.
