8T49N286-998NLGI#

Overview

The 8T49N286-998NLGI is a FemtoClock NG Universal Frequency Translator (UFT) clock synthesizer manufactured by Renesas Electronics. It supports input frequencies up to 1 GHz and provides multiple output configurations with differential capabilities. The device operates on a single 2.375V to 3.465V supply and features an I2C programming interface for flexible configuration. Designed for high-performance timing applications, it complies with GR.1244-CORE Stratum standards for ultra-low frequency jitter.

Feature Summary

• FemtoClock NG UFT technology compliant with GR.1244-CORE Stratum standards
• Supports input frequencies up to 1 GHz with multiple output options
• Single 2.375V to 3.465V power supply operation
• I2C programmable interface for custom frequency configurations

Applications

• Telecommunications infrastructure requiring low jitter clocking
• Data center networking equipment
• High-speed serial communication interfaces

Procurement Notes

Verify the exact suffix against the datasheet, as '998' typically denotes a specific factory pre-programmed frequency set. Confirm package availability and lead times directly with authorized distributors, as stock levels fluctuate. Ensure RoHS compliance documentation is obtained for procurement records.

Selection Notes

Select this component when GR.1244-CORE Stratum compliance is required for telecom applications. Compare with the 8T49N286A variant if additional features or updated revisions are needed. Verify that the pre-programmed frequency set associated with the '998' suffix matches the system requirements before ordering.

Part Context

This part belongs to the Renesas FemtoClock NG family of universal frequency translators. These devices are designed to replace traditional crystal oscillators and PLLs in high-performance systems, offering lower phase noise and greater flexibility through digital programming compared to fixed-frequency alternatives.

Replacement Considerations

The 8T49N286A series serves as a direct successor or alternative within the same product line. Check the specific order guide for pin-to-pin compatibility and feature parity between the standard 8T49N286 and the 'A' revision variants.
