8T49N008A-052NLGI8

Overview

The 8T49N008A-052NLGI8 is a programmable clock generator from the FemtoClock NG series manufactured by Renesas Electronics Corporation. It features one input and eight outputs with a maximum frequency of 300MHz. The device supports differential inputs including HCSL, LVDS, and LVPECL, while providing LVPECL outputs. It operates on a supply voltage ranging from 2.375V to 3.465V within an ambient temperature range of -40°C to 85°C. The component is housed in a 32-VFQFN package with an exposed pad.

Feature Summary

• Integrates FemtoClock NG technology for low phase jitter performance
• Supports multiple differential input signal levels for flexible reference selection
• Provides fully independent output channels configured as LVPECL

Applications

• High-speed networking equipment
• Telecommunications infrastructure
• Data center interconnects

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm pinout and electrical characteristics. Confirm end-of-life status and last-time-buy dates prior to design commitment. Ensure compatibility with existing board layouts regarding the 32-VFQFN package dimensions and thermal requirements.

Selection Notes

Select this component when eight independent LVPECL outputs are required from a single reference source. Verify that the input signal levels match the supported HCSL, LVDS, or LVPECL options. Confirm that the 300MHz maximum frequency meets system timing requirements.

Part Context

This part belongs to the FemtoClock NG family, designed for high-performance clock generation. It serves as a universal frequency translator suitable for demanding digital systems requiring precise timing synchronization across multiple data paths.

Replacement Considerations

Consult official substitution guides for compatible devices within the FemtoClock NG portfolio. Verify functional equivalence and pin compatibility before replacing obsolete inventory.
