8T49N004A-071NLGI

Overview

The 8T49N004A-071NLGI is a FemtoClock NG clock generator IC manufactured by Renesas Electronics. It operates with a maximum frequency of 2.5GHz and utilizes a single PLL circuit. The device features crystal input and LVDS output configurations, supporting a 1:4 input-to-output ratio. It is housed in a 32-VFQFN package with an exposed pad, measuring 5x5 mm. Supply voltage ranges from 2.375V to 3.465V, and it functions within a temperature range of -40°C to 85°C.

Feature Summary

• Generates high-frequency clock signals up to 2.5GHz using a single phase-locked loop architecture.
• Converts crystal inputs to differential LVDS outputs for low-jitter signal distribution.
• Integrates femtosecond jitter reduction technology to enhance signal integrity in high-speed applications.

Applications

• High-speed serial link clock generation
• Data center infrastructure timing
• Telecommunications equipment synchronization

Procurement Notes

Verify the specific suffix '071' against official Renesas documentation to confirm the exact output frequency configuration and pinout compatibility. Ensure the ordering part number matches the required datasheet revision. Confirm RoHS compliance status and lead time requirements directly with authorized distributors prior to procurement.

Selection Notes

Select this component when a 2.5GHz output frequency is required with LVDS signaling. Compare against other FemtoClock NG variants to ensure the 1:4 ratio and 32-VFQFN package meet board layout constraints. Validate that the supply voltage range aligns with the system power design.
