8T49N240-994NLGI8

Overview

The 8T49N240-994NLGI8 is a clock synthesizer and jitter attenuator manufactured by Renesas Electronics. It operates within a supply voltage range of 2.375V to 3.465V and supports output frequencies up to 867 MHz with a maximum input frequency of 875 MHz. The device utilizes a VFQFN-40 package with an exposed pad for surface mount installation. It functions as an ultra-performance jitter attenuator within the FemtoClock NG series, designed for high-frequency timing applications.

Feature Summary

• Ultra-performance jitter attenuation capabilities
• Supports output frequencies up to 867 MHz
• VFQFN-40 package with exposed pad

Applications

• High-speed serial communication systems
• Networking equipment requiring precise clocking
• Data center infrastructure

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS3 compliance status and check for relevant PCNs regarding assembly site changes or material modifications. Ensure storage conditions meet moisture sensitivity level (MSL) requirements prior to soldering.

Selection Notes

Select this component when low jitter performance is critical for signal integrity in high-speed data links. Verify that the required output frequency falls within the 867 MHz limit and that the VFQFN-40 footprint matches the PCB layout constraints. Compare against other FemtoClock NG variants if different I/O standards or pin counts are needed.

Part Context

This part belongs to the 8T49N240 family of clock synthesizers from Renesas. It shares architectural similarities with related models like the 8T49N241 and 8T49N242 but offers specific frequency and configuration options tailored for jitter-critical applications. The 'NLGI8' suffix indicates the tape and reel packaging format.

Replacement Considerations

Potential substitutes include the 8T49N241-994NLGI8 and 8T49N242-998NLGI8. Verify electrical compatibility and pinout alignment before substitution. Note that some alternatives may have different output configurations or frequency ranges.
