8T49N240-997NLGI8

Overview

The 8T49N240-997NLGI8 is a clock synthesizer and jitter cleaner from Renesas Electronics, part of the 8T49N240 series. It features four output channels with a maximum output frequency of 867 MHz and supports input frequencies up to 875 MHz. The device operates on a supply voltage ranging from 2.375 V to 3.465 V and is housed in a 40-pin VFQFN package. Designed for surface mount installation, it functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Ultra-performance jitter attenuator with four LVPECL outputs
• Maximum output frequency of 867 MHz and input frequency of 875 MHz
• Operates on a single 2.375 V to 3.465 V power supply
• Available in a compact 40-pin VFQFN exposed pad package

Applications

• High-speed serial link clock generation
• Jitter cleaning for data converters and ADCs/DACs
• Clock distribution in telecommunications infrastructure
• Networking equipment requiring low phase noise

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS3 compliance status and check for Product Change Notifications (PCNs) regarding assembly site changes or marking updates prior to procurement. Ensure the specific suffix matches required packaging and material specifications.

Selection Notes

Select this model when a four-output clock solution with high-frequency capability up to 867 MHz is required. Verify that the input source supports the specified 875 MHz maximum frequency. Ensure the design accommodates the 2.375 V to 3.465 V supply range and the thermal requirements of the 40-pin VFQFN package for the target operating environment.

Part Context

This component belongs to the 8T49N240 family of ultra-performance jitter attenuators. It shares core architectural similarities with other models in the series, such as the 8T49N240-984NLGI8, differing primarily in factory programming configurations and output characteristics defined by the specific ordering suffix.

Replacement Considerations

Direct replacements include other variants within the 8T49N240 series, such as the 8T49N240-984NLGI8. Cross-family substitution requires careful evaluation of pin compatibility, electrical parameters, and software configuration tools.
