8T49N203A-014NLGI

Overview

The 8T49N203A-014NLGI is a programmable clock generator belonging to the FemtoClock NG family, manufactured by Renesas Electronics Corporation. It functions as a frequency synthesizer and jitter attenuator, utilizing an internal Phase-Locked Loop (PLL) to generate precise output clocks from reference inputs or a crystal oscillator. The device supports multiple output configurations and is designed for high-performance timing applications requiring low phase jitter.

Feature Summary

• Supports configurable operation modes including jitter attenuation and frequency synthesis
• Features I2C programming interface for register configuration and custom part setup
• Compatible with external EEPROM for boot configuration storage

Applications

• SONET/SDH network line cards
• Ethernet network switches
• Wireless base station baseband units

Procurement Notes

Verify component authenticity through authorized distributors. Confirm RoHS compliance status and check for End-of-Life notifications prior to procurement. Ensure supply chain stability given potential discontinuation risks associated with legacy timing products.

Selection Notes

Select this model when specific output frequencies require custom factory pre-programming via order code. Evaluate compatibility with existing I2C bus architectures and verify voltage level requirements against system power rails before integration into the design.

Part Context

This component is part of the broader 8T49N203A series of programmable clock generators. It shares architectural similarities with other FemtoClock devices but is distinguished by its specific order code configuration, which defines the internal PLL settings and output frequency map at the factory.

Replacement Considerations

Consult official documentation for direct substitutes. Verify pinout and electrical parameter compatibility if considering alternative models within the same product family.
