8T49N105A-002NLGI

Overview

The 8T49N105A-002NLGI is a Universal Frequency Translator IC from the FemtoClock NG series by Renesas Electronics. It operates within a supply voltage range of 2.375V to 3.465V and utilizes a 40-VFQFN exposed pad surface mount package. The device supports a specific output frequency of 61.44MHz, designed for precision clock generation and frequency synthesis applications requiring low jitter performance.

Feature Summary

• Universal frequency translation capability for synthesizing precise clock signals
• Integration within the FemtoClock NG series for enhanced timing accuracy
• Surface mount packaging design optimized for high-density board layouts

Applications

• Frequency synthesis in digital communication systems
• Clock generation for high-speed data processing units
• Timing reference distribution in network infrastructure equipment

Procurement Notes

Verify component authenticity through authorized Renesas distributors or certified partners. Confirm that the received unit matches the exact part number suffix and package marking. Inspect the 40-VFQFN exposed pad for physical integrity before soldering. Ensure storage conditions comply with moisture sensitivity level requirements to prevent package damage during assembly processes.

Selection Notes

Select this component when a fixed 61.44MHz output is required from the FemtoClock NG family. Consider the 40-VFQFN package constraints for thermal management and PCB footprint availability. Evaluate power supply stability within the 2.375V to 3.465V range to ensure optimal jitter performance. Compare against other universal frequency translators if variable output frequencies are necessary instead of fixed synthesis.

Part Context

This model belongs to the broader 8T49N105A series of universal frequency translators. It shares architectural similarities with variants like the 8T49N105A-000NLGI and 8T49N105A-008NLGI, differing primarily in output configuration and package specifications. The FemtoClock NG branding indicates adherence to Renesas' low-jitter timing standards for demanding electronic applications.

Replacement Considerations

Direct substitutes include other 8T49N105A series variants such as 8T49N105A-000NLGI, provided the specific 61.44MHz output requirement is met. Cross-reference pinouts and electrical characteristics carefully, as suffix changes may alter functional parameters or package dimensions without changing the core device type.
