8T49N287A-993NLGI

Overview

The 8T49N287A-993NLGI is a Universal Frequency Translator (UFT) belonging to the FemtoClock NG series manufactured by Renesas Electronics. It functions as a clock generator and jitter cleaner designed for high-performance networking applications. The device supports ITU-T G.8262 Stratum E3 and GR-1244-CORE requirements, ensuring precise timing synchronization. While specific electrical parameters such as output frequencies and supply voltage are not provided in the available documentation, the component is part of the broader 8T49N287 family, which typically features multiple differential outputs and programmable configuration options via I2C interface.

Feature Summary

• Universal Frequency Translator architecture supporting flexible frequency synthesis
• Compliance with ITU-T G.8262 Stratum E3 and GR-1244-CORE standards
• Integrated jitter cleaning capabilities for signal integrity improvement
• Part of the FemtoClock NG product line for low-phase-noise performance

Applications

• Synchronous Ethernet (SyncE) network nodes
• SONET/SDH equipment requiring precise clocking
• Base station infrastructure timing distribution
• Data center synchronization systems

Procurement Notes

Verify availability status as this component may be subject to discontinuation or lifecycle changes. Confirm RoHS compliance and packaging details (Reel or Cut Tape) through official Renesas channels or authorized distributors. Ensure the ordering suffix matches the required package type and temperature range specifications before procurement.

Selection Notes

Select this model when Stratum E3 compliance and low jitter performance are critical for SyncE or SONET/SDH applications. Compare against other 8T49N287 variants based on specific output frequency requirements and pin compatibility. Verify that the I2C configuration method aligns with the system design constraints.

Part Context

This component belongs to the 8T49N287 family of Universal Frequency Translators. Similar models include the 8T49N287-998NLGI and 8T49N287-002NLGI. These devices share common architectural features but differ in factory programming configurations and specific output settings defined by their unique ordering suffixes.

Replacement Considerations

Direct replacements within the same family include the 8T49N287-998NLGI and 8T49N287-002NLGI. Cross-family alternatives from the 8T49N241 or 8T49N242 series may require schematic and firmware modifications due to differences in pinout and feature sets.
