8V44N4614NLGI8

Overview

The 8V44N4614NLGI8 is a FemtoClock NG Jitter Attenuator and Clock Generator manufactured by Renesas Electronics Corporation. It operates with a supply voltage of 3.3 V and provides 13 outputs within a package area of 49 mm². The device achieves a maximum RMS phase jitter of 0.542 ps and a typical RMS phase jitter of 0.395 ps. It supports frequency programming for generation of clock frequencies including 156.25 MHz, 125 MHz, 100 MHz, and 25 MHz individually.

Feature Summary

• FemtoClock NG technology for high-performance jitter attenuation
• Flexible frequency programming capabilities
• Multi-output clock generation architecture

Applications

• Wireless base-band systems
• High-performance system frequency generation

Procurement Notes

Verify the obsolete lifecycle status before procurement planning. Confirm availability through authorized distributors or secondary market channels as standard production has ceased. Ensure compatibility with existing 3.3 V design infrastructure and validate pinout integrity against original specifications to prevent integration errors in legacy systems.

Selection Notes

Select this component when ultra-low phase jitter performance below 0.542 ps RMS is required for sensitive timing applications. Consider the 13-output capacity and specific frequency options like 156.25 MHz or 125 MHz during design phase. Evaluate the 49 mm² package area constraints against board space limitations and verify thermal requirements for the operating environment.

Part Context

This part belongs to the FemtoClock NG family of clock generators designed for demanding digital systems. It serves as a jitter attenuator to clean up noisy input clocks. The series targets applications requiring precise timing synchronization and low phase noise performance in complex electronic architectures.

Replacement Considerations

The part is classified as obsolete. Public confirmed substitute part numbers are not available in the provided documentation. Designers must evaluate alternative clock generator families from Renesas or other manufacturers that offer similar jitter specifications and output configurations.
