9DMU0141AKILF

Overview

The 9DMU0141AKILF is a single-channel, 2:1 differential clock multiplexer designed for PCI Express (PCIe) Gen1-2-3 applications. Operating at a supply voltage of 1.5V with typical power consumption of 11mW, it accepts HCSL differential inputs and provides LP-HCSL outputs with integrated 100Ω terminations. The device supports frequencies from 1MHz to 167MHz and offers selectable asynchronous or glitch-free switching modes. It is housed in a space-saving 16-pin VFQFPN package measuring 3x3mm.

Feature Summary

• Integrated output terminations providing Zo=100 ohms for direct connection to transmission lines
• Selectable asynchronous or glitch-free switching modes
• Spread spectrum compatible for EMI reduction
• Low power consumption of 11mW typical at 1.5V operation

Applications

• PCI Express Gen1-2-3 clock distribution systems
• System-on-Chip (SOC) friendly timing solutions
• High-speed digital interface clock muxing

Procurement Notes

Verify the current manufacturing status as product lifecycle information may vary by region. Confirm that the 16-VFQFPN(3x3) package dimensions match the design footprint. Ensure compatibility with 1.5V logic levels and HCSL input requirements before integration.

Selection Notes

Select this component for low-power PCIe clock routing where board space is limited. The integrated termination resistors reduce external BOM count compared to standard HCSL devices. Verify that the 167MHz maximum frequency meets the specific PCIe generation requirements of the target application.

Part Context

This part belongs to Renesas' SOC-Friendly 1.5 V Ultra-Low-Power (ULP) PCIe family. It is functionally related to other members like the 9DMU0131 series but distinguished by its specific 1.5V operating voltage and integrated termination features optimized for modern high-speed interfaces.

Replacement Considerations

The 9DMV0141AKILFT is listed as a related active part within the same family. Verify pinout and electrical parameter compatibility if considering cross-referencing between the ULP and broader PCIe families.
