Product Introduction

Overview

The Texas Instruments XIO3130IZHC is a PCI Express ×1 3-port fanout switch, designed to provide high-performance switching capabilities within the PCI Express fabric. This component features a single ×1 upstream port and three independently configurable ×1 downstream ports, each supporting full 250-MB/s packet throughput in both directions simultaneously. The XIO3130IZHC is built with a cut-through architecture to reduce latency, enabling packets to be forwarded as soon as the address or routing information is decoded. It also supports various power management and hot plug features, making it a versatile solution for modern computing systems.

Key Features

  • Cut-Through Architecture: Reduces latency by forwarding packets as soon as the address or routing information is decoded.
  • Peer-to-Peer Support: Enables direct communication between devices connected to different downstream ports.
  • Wake Event and Beacon Support: Supports Beacon transmission and WAKE side band signal for system wake-up.
  • Active State Power Management (ASPM): Uses both L0s and L1 to manage power efficiently.
  • Integrated AUX Power Switch: Drains VAUX power only when main power is off.
  • Integrated PCI Hot Plug Support: Supports hot plug operations for downstream ports.
  • Integrated REFCLK Buffers: Provides reference clock buffers for downstream ports.
  • 3.3-V Multifunction I/O Pins: Can be used for PCI Hot Plug status and control or as general purpose I/Os.
  • Optional Serial EEPROM: For system-specific configuration register initialization.

Applications

The XIO3130IZHC is designed for use in various computing systems, including PCs and PDAs, where high-speed data transfer and efficient power management are critical. It is particularly suitable for applications requiring multiple downstream ports with independent configuration capabilities, such as in server systems, workstations, and other high-performance computing environments.

Q & A
