8T49N285NLGI8

Application Specific Clock/Timing Overview

The Renesas 8T49N285NLGI8 is a clock synthesizer and jitter cleaner belonging to the FemtoClock NG family. It is designed to meet GR.1244-CORE Stratum standards for ultra-femtosecond (UFT) applications. The device integrates a Phase-Locked Loop (PLL) to clean and distribute reference clocks, supporting low-jitter performance required by high-speed serial interfaces. Specific electrical parameters such as maximum output frequency, supply voltage range, and exact jitter metrics are not provided in the available source documentation.

Application Specific Clock/Timing Feature Summary

• Complies with GR.1244-CORE Stratum timing standards
• Ultra-femtosecond (UFT) jitter cleaning capability
• FemtoClock NG PLL technology integration

Application Specific Clock/Timing Applications

• Telecommunications infrastructure requiring Stratum-level timing
• High-speed data transmission systems
• Network synchronization equipment

Application Specific Clock/Timing Procurement Notes

Verify the specific suffix against the official datasheet, as variations like '998NLGI8' or '018NLGI' exist within the same base model series. Confirm package type and factory pre-programming configurations directly with the manufacturer or authorized distributors to ensure compatibility with system requirements.

Application Specific Clock/Timing Selection Notes

Select this component when strict adherence to GR.1244-CORE Stratum specifications is mandatory. Ensure the design supports the FemtoClock NG architecture's power and interface needs. Compare against other UFT solutions if specific jitter bandwidths or output configurations differ from the standard implementation.

Application Specific Clock/Timing Part Context

This part is part of the broader 8T49N285A series of clock synthesizers. Variants such as 8T49N285A-998NLGI8 share the same core functionality but may differ in factory programming or packaging details. The series is positioned for high-performance networking and telecom applications.

Application Specific Clock/Timing Replacement Considerations

Direct substitutes within the FemtoClock NG family include models like 8T49N241 or 8T49N242, though these belong to different sub-series with potentially different feature sets. Verify pinout and register compatibility before substitution.
