*Expected release 1Q 2007

TI’s XIO3130 is an integrated PCI Express fan-out switch solution
with one upstream x1 port and three downstream x1 ports. This high-
performance, integrated solution provides the latest in PCI Express
switch technology. It features cut-through architecture and integrated
reference clock buffers for downstream ports. The XIO3130 is fully-
compliant with the PCI Express Base Specification Rev. 1.1. It supports
Advanced Error Reporting as defined in the PCI Express base specifica-
tions and is backwards-compatible with the PCI Local Bus
Specification, Rev. 2.3.

Key Features

• PCI Express fan-out switch with x1 upstream port and three x1

downstream ports

• Fully compliant with PCI Express Base Specification, Rev. 1.1
• Cut-through architecture
• Built-in Adaptive Equalizer in each of the four ports
• Wake-event and Beacon support
• Support for D1, D2, D3hot, and D3cold
• Active State Power Management (ASPM)
• Uses both L0s and L1
• Low power PCI Express transmitter mode (pre-emphasis disabled)
• Integrated AUX Power Switch drains VAUX power only when main

power is “off”

• Integrated Hot-Plug Support
• Integrated REFCLK Buffers for Switch Downstream Ports
• Advanced Error Reporting to assist with System Debug Tools
• 3.3V Multifunction I/O pins (e.g. for Hot-Plug status-and-control, or

General Purpose I/Os)

• Listed in PCI-SIG Compliance List

Target Market

The primary purpose of the XIO3130 as a fan-out device is efficiently
expanding the chipset’s computing resources to multiple I/O ports and
enhancing system functionality and flexibility. Target applications for the
XIO3130 include PCs, servers, storage, industrial control and backplane.
