8V49NS0312NLGI

Overview

The 8V49NS0312NLGI is a clock generator from the Renesas FemtoClock NS series, designed for high-performance timing applications. It features 12 outputs with a maximum frequency of 2.5 GHz and supports up to 50 MHz input frequencies. The device operates within a supply voltage range of 3.135 V to 3.465 V and consumes approximately 73 mA. Packaged in a VFQFN-64 format, it functions reliably between -40°C and +85°C. Key performance metrics include a maximum duty cycle of 60% and jitter specifications reaching as low as 87 fs.

Feature Summary

• Generates 12 output clocks with a maximum frequency of 2.5 GHz
• Supports input frequencies up to 50 MHz
• Operates on a single 3.3 V power supply (3.135 V to 3.465 V)
• Low jitter performance down to 87 fs

Applications

• High-speed data communication systems
• Networking equipment requiring precise clock distribution
• Server and storage infrastructure timing

Procurement Notes

Verify the specific suffix 'NLGI' against official Renesas documentation to confirm package type and temperature grade. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as regulatory details may vary by production batch. Ensure ordering quantities align with available packaging formats such as trays or reels.

Selection Notes

Select this component when 12 synchronized outputs are required at frequencies up to 2.5 GHz. The 8V49NS0312NLGI is suitable for designs needing low jitter performance under a standard 3.3 V supply. Verify that the VFQFN-64 package dimensions fit the PCB layout constraints and that the operating temperature range meets the environmental requirements of the target application.

Part Context

This part belongs to the FemtoClock NS family, which specializes in low-jitter clock generation and distribution. The 8V49NS0312 variant specifically provides multiple dividers and outputs to support complex system timing architectures. It serves as a critical component for maintaining signal integrity in high-bandwidth digital interfaces.

Replacement Considerations

Consult the official Renesas cross-reference guide for verified substitutes. Generic replacements may not match the specific 12-output configuration or the 2.5 GHz maximum frequency capability.
