XIO2001ZWS

Specialized Overview

The XIO2001ZWS 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 integrates an internal arbiter supporting up to six downstream PCI bus controllers, eliminating the need for external arbitration hardware. It features an integrated buffer clock to reduce bill of materials costs and includes adaptive equalization to improve jitter tolerance. This allows for longer PCB traces or extended cable lengths in high-speed designs.

Specialized Feature Summary

• Integrates an internal arbiter supporting up to six downstream PCI bus controllers without requiring external arbitration devices.
• Includes an integrated buffer clock, removing the necessity for external clock buffers and reducing component count.
• Features built-in adaptive equalization to enhance jitter tolerance and support longer signal paths.

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 ZWS against the official datasheet to confirm package type and temperature range. Ensure compatibility with existing system requirements before procurement. Check for end-of-life status or recommended new design alternatives if applicable.

Specialized Selection Notes

Select this component when migrating legacy PCI designs to PCI Express while minimizing board space. Consider the integrated arbiter and clock features if external components are undesirable. Verify that the required number of downstream controllers does not exceed the internal six-controller limit.

Specialized Part Context

The XIO2001 is part of Texas Instruments' interface product line designed for bridge applications. It serves as a single-function bridge to simplify the transition from PCI to PCI Express technologies. The device is positioned to offer high throughput in a compact form factor compared to similar competitive products.

Specialized Replacement Considerations

The XIO2000 and XIO2000A are documented as similar PCI Express to PCI translation bridges from Texas Instruments. These may serve as functional alternatives depending on specific pinout and feature requirements.
