XIO2001IZWS

Specialized Overview

The XIO2001IZWS is a single-function PCI Express to PCI translation bridge manufactured by Texas Instruments. It operates in a 169-ball ZWS nFBGA package with dimensions of 12.00 mm x 12.00 mm. The device supports full ×1 PCI Express throughput at 250 MB/s per direction and provides full PCI Local Bus 66-MHz/32-Bit throughput. It features an internal configurable arbiter supporting up to six subordinate PCI bus masters, advanced error reporting including ECRC, and active-state link power management using L0s and L1 states. The bridge accepts either a 100-MHz differential or 125-MHz single-ended reference clock.

Specialized Feature Summary

• Supports migration from conventional PCI to PCI Express technology with compliance to relevant bridge specifications.
• Includes an internal arbiter for up to six external PCI masters, eliminating the need for external arbitration hardware.
• Integrates buffered clock outputs and adaptive equalization to improve signal integrity over longer PCB traces.

Specialized Applications

• Enterprise systems such as data center and enterprise computing infrastructure
• Personal electronics including PC and notebook computers
• Industrial applications like factory automation, retail automation, and industrial transport
