8T49N205A-011NLGI8

Overview

The 8T49N205A-011NLGI8 is a FemtoClock NG clock synthesizer and jitter cleaner from Renesas Electronics. It features an ultra-low fractional (UFT) architecture with phase build-out capabilities, designed to provide precise frequency synthesis and signal conditioning. The device integrates an on-chip EEPROM for configuration storage and supports flexible input/output configurations. It operates within standard voltage ranges and utilizes a compact package suitable for high-density PCB layouts.

Feature Summary

• Ultra-low fractional phase build-out architecture for precise frequency generation
• Integrated non-volatile EEPROM for persistent configuration storage
• Jitter cleaning and attenuation capabilities for signal integrity enhancement

Applications

• FPGA timing and control applications
• High-speed serial link synchronization
• Telecommunications infrastructure equipment
• Industrial control systems requiring low jitter clocks

Procurement Notes

Verify the specific suffix '011' against the official Renesas datasheet to confirm the exact output frequency and pinout configuration. Ensure compatibility with the target system's voltage levels and interface requirements before procurement. Confirm that the component meets all necessary environmental and reliability standards for the intended application environment.

Selection Notes

Select this component when ultra-low fractional synthesis and jitter cleaning are required in a single package. It is suitable for designs needing flexible frequency generation without external components for basic operation. Consider the integrated EEPROM feature if configuration persistence across power cycles is necessary for the system design.

Part Context

This part belongs to the FemtoClock NG family of clock generators and jitter cleaners. The family is known for high performance and low jitter, widely used in datacom, telecom, and industrial applications. The 8T49N205A variant specifically offers UFT capabilities, distinguishing it from integer-only or other fractional variants in the lineup.

Replacement Considerations

Check for direct substitutes within the 8T49N2xx series or the newer RC3xxx FemtoClock 3 series. Verify pin-to-pin compatibility and electrical parameter equivalence. Consult the Renesas cross-reference guide for officially confirmed replacement part numbers.
