8T49N240-025NLGI8

Overview

The Renesas 8T49N240-025NLGI8 is a FemtoClock NG jitter attenuator and clock synthesizer. It operates within a supply voltage range of 2.375V to 3.465V and supports input frequencies up to 875 MHz with maximum output frequencies reaching 867 MHz. The device features four differential outputs and utilizes a VFQFPN-40 (6x6) package. It functions across an industrial temperature range of -40°C to +85°C, consuming approximately 40 mA of operating current.

Feature Summary

• Integrates low-jitter attenuation capabilities for signal integrity enhancement
• Supports multiple input formats including LVPECL, LVDS, and HCSL
• Provides four differential output channels for multi-clock distribution
• Includes onboard EEPROM for configuration storage

Applications

• High-speed serial link clock generation
• Data center infrastructure timing
• Telecommunications equipment synchronization
• Network switch and router clocking

Procurement Notes

Verify the specific suffix '025' against official Renesas documentation to confirm exact frequency configurations and pinout compatibility. Confirm availability status as this series may have limited stock or obsolescence notices. Ensure ESD handling protocols are followed during installation due to the fine-pitch VFQFPN package requirements.

Selection Notes

Select this component when ultra-low jitter performance is required for high-speed interfaces. Compare against other FemtoClock NG variants based on specific input/output frequency ratios and package constraints. Verify that the 40-pin form factor fits the target PCB layout and that the 3.3V nominal supply aligns with system power rails.

Part Context

This part belongs to the Renesas FemtoClock NG family, designed for precision clocking applications. It complements other models like the 8T49N240-027NLGI8 by offering similar jitter attenuation but with distinct programming configurations. The series is widely used in networking and storage systems requiring precise clock synthesis.

Replacement Considerations

Check for direct substitutes within the 8T49N240 series such as the 8T49N240-027NLGI8. Verify if newer revisions or alternative packages from the same family meet the electrical specifications. Consult Renesas PCNs for any assembly site changes or material updates that might affect compatibility.
