8T49N285A-998NLGI8

Overview

The Renesas 8T49N285A-998NLGI8 is a clock synthesizer and jitter cleaner belonging to the FemtoClock NG UFT GR.1244 Stratum standard series. It integrates low-phase noise frequency translation and jitter attenuation capabilities for networking applications. The device supports multiple output configurations and includes alarm and monitoring functions suitable for high-performance communication systems.

Feature Summary

• FemtoClock NG technology compliant with GR.1244-CORE Stratum standards
• Integrated jitter cleaning and frequency synthesis capabilities
• Supports I2C programming interface for register configuration
• Includes alarm and monitoring functions for system diagnostics

Applications

• Networking equipment requiring Stratum timing compliance
• Telecommunications infrastructure systems
• High-speed data transmission interfaces

Procurement Notes

Verify component authenticity through authorized distributors as counterfeits exist in the market. Confirm RoHS3 compliance status prior to procurement. Check for Product Change Notifications (PCN) regarding assembly site or material changes. Ensure moisture sensitivity level (MSL) handling procedures are followed during storage and assembly processes.

Selection Notes

Select this model when GR.1244 Stratum compliance is mandatory for network synchronization. Verify that the integrated PLL bandwidth and jitter performance meet specific application requirements. Consider the I2C interface compatibility with existing control logic. Evaluate power supply voltage requirements against available system rails.

Part Context

This part belongs to the 8T49N285A family of Universal Frequency Translators. It shares core FemtoClock NG architecture with other variants in the series, differing primarily in pre-programmed frequency configurations and specific output pin assignments defined by the order code suffix.

Replacement Considerations

Direct replacements within the same family include 8T49N287-998NLGI8. Verify functional equivalence regarding output frequencies and package dimensions before substitution. Cross-reference datasheets for any differences in electrical characteristics or pinout definitions.
