Overview
The XIO1100ZWSR is a PCI Express (PCIe) PHY (Physical Layer) device manufactured by Texas Instruments. It is designed to interface the PCI Express Media Access Layer (MAC) to a PCI Express serial link, complying with the PCI Express Base Specification Revision 1.1. This device uses a modified version of the PIPE interface, referred to as the TI-PIPE interface, which is pin-configurable as either a 16-bit or an 8-bit interface. The XIO1100ZWSR is no longer in production, and new designs should consider alternative products.
