8T49N524-002NLGI8

Overview

The 8T49N524-002NLGI8 is a dual fractional clock generator from Renesas Electronics, housed in a 40-VFQFN Exposed Pad package. It operates within a supply voltage range of 2.375V to 3.465V and supports an operating temperature from -40°C to 85°C. The device provides selectable LVDS or LVPECL outputs with a 1:8 input-to-output ratio.

Feature Summary

• Dual clock generator architecture supporting any-rate frequency synthesis
• Selectable output interface options including LVDS and LVPECL
• Fractional clock generation capability for flexible frequency planning

Applications

• Telecommunications infrastructure requiring precise clock distribution
• Data center networking equipment needing low jitter solutions
• Industrial systems utilizing programmable timing signals

Procurement Notes

Verify component authenticity through authorized distributors as the lifecycle status is listed as obsolete. Confirm package integrity and pin compatibility during replacement sourcing. Request original manufacturer documentation to validate specifications against current design requirements before procurement.

Selection Notes

Evaluate the dual generator structure against single-channel alternatives for system complexity. Consider the specific output drive requirements of LVDS versus LVPECL for target loads. Assess thermal performance within the specified -40°C to 85°C range for the intended application environment.

Part Context

This component belongs to the FemtoClock NG series, designed for high-performance clock generation. It serves as a programmable solution for synthesizing multiple frequencies from a single reference, replacing discrete oscillator setups in modern electronic designs requiring precise timing.

Replacement Considerations

Consult official cross-reference lists for direct substitutes. Verify electrical parameters and pinout compatibility when selecting alternative dual clock generators from other manufacturers.
