8T49N286A-998NLGI#

Overview

The 8T49N286A-998NLGI is a clock synthesizer and jitter cleaner from the FemtoClock NG UFT series by Renesas Electronics. Designed to meet GR.1244-CORE Stratum standards, it supports up to five inputs and eight outputs with a maximum frequency of 1 GHz. The device operates on a single 3.3 V supply and features an I2C interface for configuration. It utilizes a 72-pin VFQFN package with an exposed pad, suitable for surface-mount applications in demanding timing environments.

Feature Summary

• Supports up to 5 differential or single-ended inputs and 8 differential or single-ended outputs
• Complies with GR.1244-CORE Stratum timing standards
• Features integrated EEPROM for non-volatile configuration storage
• Operates within a -40°C to +85°C temperature range

Applications

• Telecommunications infrastructure requiring Stratum-level synchronization
• Base station equipment needing low-jitter clock distribution
• High-speed data transmission systems
• Network synchronization nodes

Procurement Notes

Verify the specific suffix '8' against official documentation to confirm packaging details, as suffixes often denote reel versus tray configurations. Confirm current availability status directly with authorized distributors, as lead times may vary. Ensure compliance with RoHS directives and check moisture sensitivity levels before handling.

Selection Notes

Select this component when strict adherence to GR.1244-CORE Stratum specifications is required for network synchronization. Compare input/output ratios and voltage levels against system requirements. Consider the 72-VFQFN package constraints for PCB layout and thermal management during the design phase.

Part Context

This part belongs to the 8T49N286A family within the FemtoClock NG Universal Frequency Translator line. It shares architectural similarities with other models in the series but is distinguished by its specific input/output count and Stratum compliance capabilities. It serves as a specialized solution for high-performance timing applications.

Replacement Considerations

Consult the official FemtoClock NG order guide for direct pin-compatible alternatives within the same family. Verify that any substitute part maintains identical Stratum compliance and output frequency capabilities.
