Overview
The XIO2001IZGUR, produced by Texas Instruments, is a single-function PCI Express (PCIe) to PCI bus translation bridge. This component is fully compliant with the PCI Express to PCI/PCI-X Bridge Specification, Revision 1.0, and the PCI Express Base Specification, Revision 2.0. It supports a ×1 PCIe link operating at full 250 MB/s packet throughput in each direction simultaneously. The XIO2001IZGUR is designed to bridge the gap between PCIe and legacy PCI systems, enabling seamless communication and data transfer between these two bus standards.
