XIO3130INMH

Specialized Overview

The XIO3130INMH is an integrated PCI Express (PCIe) 1:3 four-port, four-lane packet switch manufactured by Texas Instruments. It features a single x1 upstream port and three independently configurable x1 downstream ports, supporting full 250 MB/s packet throughput in each direction per link. The device operates within a temperature range of -40 °C to 85 °C and utilizes a 196-pin LBGA package measuring 14x14 mm. It complies with PCI Express Base Specification Revision 1.1 and supports standard power management states including ASPM L0/L1.

Specialized Feature Summary

• Supports direct-through architecture for reduced latency by forwarding packets immediately upon header decoding.
• Integrates PCI hot-plug compatible controller allowing independent configuration of downstream ports for slot power control.
• Enables active state power management (ASPM) with automatic L0 and L1 state transitions during idle periods.
• Includes integrated REFCLK buffer for downstream ports and AUX power switch functionality.

Specialized Applications

• Expanding PCIe connectivity in embedded systems requiring multiple x1 devices.
• Implementing hot-pluggable peripheral slots in industrial or server hardware.
• Creating low-latency data routing paths in communication equipment.

Specialized Procurement Notes

Verify the specific suffix 'INMH' against official Texas Instruments documentation to confirm pinout, package dimensions, and environmental ratings. Ensure compatibility with system voltage requirements of 3.3V nominal supply. Check for RoHS compliance status and moisture sensitivity level classification prior to procurement.

Specialized Selection Notes

Select this component when a single PCIe root complex needs to fan out to three independent endpoints without protocol conversion. It is suitable for designs requiring hot-plug support and power management features inherent to PCIe 1.1 specifications. Consider the 196-ball BGA footprint constraints during PCB layout planning.

Specialized Part Context

This part belongs to the XIO3130 family of PCIe switches designed for high-performance data transfer. It serves as a bridge between a host processor and multiple peripheral devices, enabling efficient bandwidth utilization across parallel lanes while maintaining signal integrity through integrated buffering and termination.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify functional equivalence with other PCIe 1.1 x1-to-x1 switches if alternative sourcing is required.
