XIO3130IZHC

Specialized Overview

The XIO3130IZHC is a PCI Express (PCIe) 1:3 four-port, four-channel fanout switch manufactured by Texas Instruments. It provides one PCIe x1 upstream port and three independently configurable downstream ports. The device supports full 250 MB/s packet throughput in each direction for all ports. It operates with a nominal supply voltage of 3.3V and functions within an operating temperature range of -40°C to 85°C. The component is housed in a QFN package.

Specialized Feature Summary

• Supports PCI Express Base Specification Revision 1.1
• Features a direct-through architecture to minimize latency
• Includes integrated PCI hot-plug support mechanisms
• Provides active state power management capabilities

Specialized Applications

• PCI Express fanout switching
• System expansion via PCIe slots
• Hot-pluggable peripheral integration

Specialized Procurement Notes

Verify the specific suffix 'IZHC' against official Texas Instruments documentation to confirm pinout compatibility and thermal specifications. Ensure the source document explicitly identifies this part as a PCIe switch rather than a generic bridge or PHY component. Cross-reference the manufacturer's current product status to confirm availability and lifecycle stage before procurement planning.

Specialized Selection Notes

Select this component when a single PCIe x1 link requires expansion into multiple downstream connections. Verify that the system design accommodates the 3.3V supply requirement and the specified temperature range. Confirm that the downstream devices are compatible with PCIe x1 signaling speeds and that the integrated hot-plug features meet the system's power sequencing requirements.

Specialized Part Context

This device belongs to the XIO series of PCI Express switches from Texas Instruments. It serves as a bridge between a host processor's PCIe root complex and multiple endpoint devices. The component facilitates signal distribution while maintaining protocol integrity across the expanded links.
