9DMU0131AKILFT

Overview

The 9DMU0131AKILFT is a discontinued PCI Express (PCIe) clock multiplexer manufactured by Renesas Electronics Corporation. It functions as a 2:1 mux with one output, operating at frequencies up to 167 MHz. The device utilizes LVDS differential inputs and provides LP-HCSL differential outputs. It operates on a single 1.5V supply voltage within the range of 1.425V to 1.575V. The component is housed in a 16-VFQFPN package with dimensions of 3x3 mm and includes an exposed pad for thermal management. It supports an operating temperature range from -40°C to +85°C.

Feature Summary

• 2:1 Multiplexing Ratio: Selects between two differential input sources for a single differential output.
• PCIe Compliance: Designed specifically for PCI Express applications supporting Gen1-3 standards.
• Low Voltage Operation: Functions at 1.5V with a supply range of 1.425V to 1.575V.
• Compact Packaging: Utilizes a space-saving 16-VFQFPN (3x3 mm) surface-mount package.

Applications

• PCI Express clock distribution systems
• Server and storage backplane designs
• High-speed digital interface timing circuits

Procurement Notes

This specific part number is officially obsolete and no longer in production. Verification of availability should focus on surplus or secondary market channels rather than direct manufacturer stock. Buyers must confirm the authenticity of any available units through authorized distributors. Replacement components are recommended for new designs due to the discontinuation status.

Selection Notes

Designers requiring active procurement options should consider the 9DMV0131BKILF, which is listed as a manufacturer-recommended replacement. When selecting alternatives, ensure compatibility with the required 167 MHz frequency, LVDS input signaling, and LP-HCSL output requirements. Verify that the substitute component matches the 16-VFQFPN package footprint if board space constraints are critical.

Part Context

The 9DMU0131 belongs to the IDT SOC-Friendly 1.5 V Ultra-Low-Power PCIe family, now integrated into Renesas Electronics' portfolio following acquisitions. This series targets system-on-chip architectures requiring low power consumption and minimal external components for clock routing in high-performance computing environments.

Replacement Considerations

The 9DMV0131BKILF is identified as a manufacturer-recommended alternative. Users should verify pinout compatibility and electrical specifications against the original datasheet before substitution.
