8T49N524-003NLGI8

Overview

The 8T49N524-003NLGI8 is a dual fractional clock generator from the FemtoClock NG series, manufactured by Renesas Electronics. It operates within a supply voltage range of 2.375V to 3.465V and supports an operating temperature range of -40°C to 85°C. The device features a single input and two outputs, with a maximum output frequency of 158.95MHz. It is housed in a 40-VFQFN package with an exposed pad.

Feature Summary

• Generates independent output frequencies decoupled from each other and the input source
• Supports factory-programmed default frequencies or serial port reprogramming

Applications

• High-performance computing systems requiring precise clock synthesis
• Telecommunications infrastructure equipment
• Data center networking applications

Procurement Notes

Verify component authenticity through authorized channels. Confirm RoHS compliance status and check for Product Change Notifications regarding package or assembly site updates. Ensure storage conditions meet moisture sensitivity level requirements before soldering.

Selection Notes

Select this model when dual independent frequency generation is required without external dividers. Consider the 40-VFQFN package constraints and thermal dissipation needs. Verify that the 158.95MHz maximum frequency meets system timing requirements.

Part Context

This component belongs to the FemtoClock NG series, designed for low-jitter clock generation. It serves as a programmable solution for synthesizing multiple clock domains from a single reference, replacing discrete PLL and divider combinations in complex digital systems.

Replacement Considerations

Consult official substitution guides for cross-reference part numbers. Verify pin compatibility and electrical specifications before replacement.
