9DMU0441AKILF

Overview

The 9DMU0441AKILF is a clock multiplexer from the IDT SOC-Friendly 1.5 V Ultra-Low-Power PCIe Gen1-2-3 family. It features two differential HCSL inputs and one differential LP-HCSL output with integrated 100Ω terminations for direct connection to transmission lines. The device operates at frequencies between 1 MHz and 167 MHz with a typical power consumption of 11 mW at 1.5 V. It supports spread spectrum input for EMI reduction and offers selectable asynchronous or glitch-free switching modes. The component is housed in a space-saving 3x3 mm 16-pin VFQFPN package.

Feature Summary

• Ultra-low-power operation at 1.5 V with typical consumption of 11 mW
• Integrated 100Ω output terminations eliminate external resistors
• Selectable asynchronous or glitch-free switching modes
• Spread spectrum compatible for EMI reduction

Applications

• PCI Express Gen1, Gen2, and Gen3 systems
• Low-power server and storage architectures
• SOC-friendly clock distribution networks

Procurement Notes

Verify the specific suffix AKILF against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with 1.5V supply rails and HCSL signaling levels required by the target PCIe interface. Cross-reference RoHS compliance status with the latest environmental declarations prior to final procurement authorization.

Selection Notes

Select this component for designs requiring minimal board space and low power dissipation in PCIe Gen1-3 applications. The integrated termination simplifies layout compared to standard HCSL devices. Verify that the 167 MHz maximum frequency meets system requirements. Consider the 1.5V operating voltage when designing power delivery networks relative to legacy 3.3V solutions.

Part Context

This part belongs to the 9DMU/V series of ultra-low-power PCIe clock multiplexers. It replaces older 3.3V HCSL devices, offering significant reductions in power consumption and board area. The 1.5V architecture aligns with modern SOC power domains, facilitating direct integration without level shifting for compatible logic families.
