8V44N004NLGI

Overview

The 8V44N004NLGI is a FemtoClock NG Universal Frequency Translator manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 2.375V to 3.465V and supports input signal types including HCSL, LVDS, and LVPECL. The device provides four differential LVPECL outputs with a maximum frequency of 300MHz. Packaged in a 32-VFQFN (5x5mm) exposed pad format, it functions as a clock generator with a 1:4 input-to-output ratio. The component is designed for surface mount installation and operates across a temperature range of -40°C to 85°C.

Feature Summary

• Fourth-generation FemtoClock NG technology for low phase noise performance
• Supports multiple input formats: HCSL, LVDS, and LVPECL
• Four differential LVPECL output channels
• I2C serial interface for register programming and configuration

Applications

• Networking equipment requiring precise clock distribution
• Telecommunications infrastructure systems
• High-speed data processing applications

Procurement Notes

Verify the specific ordering suffix against the official IDT/Renesas FemtoClock NG Ordering Guide to confirm pinout, package dimensions, and factory-set configurations. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements during storage and handling. Check for obsolescence notices or product change notifications regarding assembly sites.

Selection Notes

Select this component when a universal frequency translator with mixed-mode input support (HCSL/LVDS/LVPECL) is required. Ensure the design accommodates the 32-VFQFN package thermal requirements via the exposed pad. Verify that the target application utilizes LVPECL signaling for the four output channels and operates within the specified 2.375V to 3.465V power supply range.

Part Context

This part belongs to the FemtoClock NG family of programmable clock generators. It serves as a frequency translator capable of accepting various input clock standards and generating synchronized differential outputs. The device integrates a PLL with bypass capabilities and allows for customized power-up defaults via one-time programmable ROM settings.

Replacement Considerations

Consult the official Renesas cross-reference guide for verified substitutes. Consider other members of the 8V44N004 series or the 8T49N004A series if pin compatibility or specific output configurations differ. Verify that any replacement maintains the same 32-VFQFN package and electrical specifications.
