8T49N285A-999NLGI8

Overview

The Renesas 8T49N285A-999NLGI8 is a FemtoClock NG Universal Frequency Translator (UFT) clock synthesizer and jitter cleaner. It complies with GR.1244-CORE Stratum standards for ultra-low frequency applications. The device features a programmable PLL architecture capable of generating precise clock signals from various input references. It supports multiple output formats to interface with high-speed digital components in telecommunications infrastructure.

Feature Summary

• Complies with Telcordia GR.1244-CORE Stratum timing standards
• Integrates low-jitter VCO and programmable PLL for signal conditioning
• Supports flexible input/output configurations via I2C programming
• Designed for telecom equipment requiring precise frequency translation

Applications

• Telecommunications base stations
• Synchronous Ethernet networks
• SONET/SDH transmission systems
• Carrier-grade networking equipment

Procurement Notes

Verify the specific suffix '999' against official Renesas documentation to confirm factory-programmed register settings, as order codes define unique internal configurations. Confirm current production status and lead times directly with authorized distributors, as availability for specific pre-programmed variants may vary.

Selection Notes

Select this model when GR.1244 Stratum compliance is required for carrier-class timing. Ensure the pre-programmed frequency set matches the system requirements, as custom reprogramming may be needed if the fixed configuration does not align with the target application frequencies.

Part Context

This component belongs to the FemtoClock NG family, which utilizes fourth-generation PLL technology to achieve ultra-low phase jitter. The 8T49N285A series is specifically engineered for universal frequency translation in high-performance telecommunications environments.

Replacement Considerations

Check for updated suffixes or newer generation UFT devices within the 8T49N28x series that may offer improved performance or availability while maintaining pin compatibility and functional equivalence.
