8T49N004A-059NLGI

Overview

The 8T49N004A-059NLGI is a programmable clock generator from the FemtoClock NG series, manufactured by Renesas Electronics Corporation. It features one circuit with a maximum frequency of 300MHz and supports differential input/output configurations. The device accepts HCSL, LVDS, or LVPECL inputs and provides LVPECL outputs in a 1:4 ratio. It operates on a supply voltage of 2.375V to 3.465V within an industrial temperature range of -40°C to 85°C. Packaged in a 32-VFQFN (5x5) exposed pad, it includes a PLL with bypass functionality.

Feature Summary

• Supports multiple input formats including HCSL, LVDS, and LVPECL for flexible system integration.
• Generates precise LVPECL output signals with a 1:4 input-to-output ratio.
• Integrates a Phase-Locked Loop (PLL) with bypass capability for optimized jitter performance.
• Designed for high-speed applications requiring accurate timing and signal distribution.

Applications

• High-speed data communication systems
• Network infrastructure equipment
• Server and storage subsystems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and moisture sensitivity level (MSL 3) handling requirements during storage and assembly. Ensure compatibility with RoHS3 and REACH regulations. Cross-reference part numbers carefully as variants exist within the FemtoClock NG family. Validate electrical specifications against specific application timing requirements before finalizing procurement decisions.

Selection Notes

Select this component when precise low-jitter clock generation is required for high-speed digital interfaces. Consider the 300MHz maximum frequency and LVPECL output drive strength for signal integrity needs. Evaluate the 32-VFQFN package constraints for PCB layout and thermal management. Verify that the available input formats match the source clock standards in the design. Assess power supply stability within the 2.375V to 3.465V operating range.
