8T49N285-998NLGI8

Overview

The Renesas 8T49N285-998NLGI8 is a FemtoClock NG UFT clock synthesizer and jitter cleaner designed for high-performance timing applications. It complies with GR.1244-CORE Stratum standards, making it suitable for ultra-femtosecond (UFT) requirements. The device integrates a PLL frequency synthesizer to generate precise clock signals from various input sources. It features an onboard EEPROM for configuration storage, allowing for flexible setup without external memory components. This component is part of the 8T49N285A series, optimized for low jitter performance in telecommunications and data infrastructure.

Feature Summary

• Complies with GR.1244-CORE Stratum standard for ultra-femtosecond jitter performance
• Integrates onboard EEPROM for non-volatile configuration storage
• Functions as both a clock synthesizer and jitter cleaner
• Supports multiple input/output clock formats via programmable PLL

Applications

• Telecommunications base stations requiring Stratum-compliant timing
• Data center infrastructure needing low-jitter clock distribution
• High-speed serial communication links
• Network synchronization equipment

Procurement Notes

Verify the exact suffix against the datasheet, as '998' typically denotes specific output frequencies or package variants. Confirm moisture sensitivity level (MSL) and reflow soldering profile requirements prior to assembly. Check for recent Product Change Notices (PCNs) regarding manufacturing site changes or material updates. Ensure the ordering quantity matches the manufacturer's standard packaging specifications.

Selection Notes

Select this model when GR.1244 Stratum compliance is mandatory for network synchronization. Compare jitter attenuation capabilities against other FemtoClock NG devices if lower phase noise is required. Verify that the available input frequencies match the system's reference clock sources. Consider the 8T49N285A series alternatives if different pin counts or output configurations are needed.

Part Context

This component belongs to the Renesas FemtoClock NG family, which specializes in precision timing solutions. The 8T49N285A series is engineered for applications demanding superior jitter cleaning and synthesis. It complements other Renesas timing products by offering integrated EEPROM management and robust Stratum-level performance for critical infrastructure.

Replacement Considerations

The 8T49N285A-999NLGI8 is listed as a similar alternative in distributor catalogs. Verify electrical compatibility and pinout alignment before substitution. Other members of the 8T49N285A family may offer different I/O counts or power profiles.
