9DMV0441AKILFT

Overview

The 9DMV0441AKILFT is a clock distribution IC from Renesas Electronics, designed for PCI Express Gen1-2-3 applications. It operates as a 2:4 clock multiplexer with a maximum output frequency of 200 MHz. The device functions on a 1.7 V to 1.9 V supply voltage and utilizes LVDS differential inputs to generate LP-HCSL differential outputs. Packaged in a 24-pin VFQFPN (4x4 mm) surface-mount format, it supports both asynchronous and glitch-free switching modes. The component is rated for industrial operating temperatures ranging from -40°C to +85°C.

Feature Summary

• Integrated 100 ohm output terminations eliminate the need for external resistors
• Supports selectable asynchronous or glitch-free switching modes
• Compatible with spread spectrum modulation for EMI reduction
• Each of the four outputs features a dedicated OE# pin for power management

Applications

• PCI Express Gen1, Gen2, and Gen3 systems
• Servers and storage arrays
• Automated Test Equipment (ATE)
• Master/Slave clocking architectures

Procurement Notes

Verify the specific suffix 'AKILFT' against the manufacturer's current datasheet to confirm package type and temperature grade. Confirm RoHS compliance status and Moisture Sensitivity Level (MSL 3) requirements during handling. Check for any Product Change Notifications (PCN) regarding assembly sites or labeling changes that may affect long-term sourcing stability.

Selection Notes

Select this component when a low-power 1.8V PCIe clock solution with integrated termination is required. Ensure the design accommodates LVDS input signals and LP-HCSL output loads. Verify that the 200 MHz maximum frequency meets system timing requirements. Consider the 24-pin VFQFPN footprint constraints during PCB layout planning.

Part Context

This part belongs to the IDT SOC-Friendly 1.8 V Very-Low-Power (VLP) PCIe family. It serves as a direct replacement for legacy clock muxes by reducing board space and component count through integrated terminations. The device is manufactured by Renesas Electronics Corporation following their acquisition of IDT semiconductor assets.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate other members of the 9DMV0441 series or 9DML04 series only if voltage levels and interface compatibility allow.
