XIO3130ZHC

Specialized Overview

The XIO3130ZHC is a PCI Express (PCIe) 1:3 four-port, four-channel fan-out switch manufactured by Texas Instruments. It features one ×1 upstream port and three independently configurable ×1 downstream ports. The device supports full 250 MB/s packet throughput in each direction for both upstream and downstream links. It implements a cut-through architecture to minimize latency associated with PCIe data packets. The component complies with the PCI Express Base Specification Revision 1.1 and operates within an ambient temperature range of -40°C to 85°C. It utilizes a single 3.3V supply voltage nominal input.

Specialized Feature Summary

• Cut-through switching architecture for reduced latency
• Integrated PCI hot-plug compatible controller
• Support for Active State Power Management (ASPM) L0 and L1 states
• Configurable downstream ports for independent system design

Specialized Applications

• PCI Express fan-out expansion systems
• Systems requiring PCI hot-plug slot implementation
• Low-latency data routing applications

Specialized Procurement Notes

Verify the specific suffix ZHC against the manufacturer's official datasheet to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints and signal integrity requirements for PCIe x1 lanes. Confirm that the sourcing channel provides genuine components with traceable documentation.

Specialized Selection Notes

Select this component when a single PCIe root complex port needs to drive multiple endpoint devices without significant latency penalty. Consider the integrated power management and hot-plug features if system flexibility and power efficiency are required. Verify that the downstream devices support the PCIe 1.1 specification standards.

Specialized Part Context

The XIO3130 series belongs to Texas Instruments' portfolio of high-performance bridge and switch solutions for peripheral connectivity. This specific model addresses the need for expanding PCIe connectivity in compact form factors while maintaining standard protocol compliance and power management capabilities.

Specialized Replacement Considerations

Check for direct pin-to-pin replacements such as the TSB81AE or other TI PCIe switches. Verify electrical compatibility and software configuration registers before substitution.
