XIO3130NMH

Specialized Overview

The XIO3130NMH is a PCI Express (PCIe) switch manufactured by Texas Instruments, designed to expand system connectivity. It features one PCIe x1 upstream port and three downstream ports, supporting full 250 MB/s packet throughput in each direction per link. The device operates within a supply voltage range of 3.3V nominal and an ambient temperature range of -40°C to +85°C. It utilizes a VQFN package with 64 pins, facilitating surface-mount installation. The component supports SPI and UART interfaces for configuration and control.

Specialized Feature Summary

• Supports PCI Express Base Specification Revision 1.1 and Card Electromechanical Specification Revision 1.1
• Implements a direct-through architecture to minimize latency associated with packet forwarding
• Includes integrated PCI hot-plug compatible controller for downstream port power management
• Features integrated REFCLK buffer for switch downstream ports

Specialized Applications

• Expanding PCIe connectivity in embedded systems
• Connecting multiple PCIe devices in compact hardware designs
• Systems requiring low-latency data transfer between peripherals

Specialized Procurement Notes

Verify the specific suffix NMH against official datasheets to confirm pinout and package dimensions. Ensure compatibility with the target PCB layout and thermal requirements. Confirm that the operating environment stays within the specified -40°C to +85°C range. Check for moisture sensitivity levels if storage conditions are not controlled. Validate interface signals against the system design specifications.

Specialized Selection Notes

Select this component when a single upstream connection must fan out to three downstream PCIe x1 links. Consider the 250 MB/s per-direction bandwidth limit for data throughput requirements. Evaluate the VQFN-64 package size against available board space. Ensure the system design accommodates the 3.3V supply requirement and thermal dissipation needs for the operating temperature range.

Specialized Part Context

The XIO3130 belongs to the SimpleLink family of microcontrollers and connectivity solutions from Texas Instruments. While primarily a switch, it integrates with ARM-based systems often found in IoT and industrial applications. It complements other TI components like the CC3130 for networked environments, providing both wireless connectivity and wired expansion capabilities.
