8T49N008A-063NLGI

Overview

The 8T49N008A-063NLGI is a high-frequency clock generator IC from the FemtoClock NG series by Renesas Electronics. It features fourth-generation PLL technology and supports a maximum output frequency of 1.228GHz. The device provides eight selectable outputs in LVDS or LVPECL formats. Input options include HCSL, LVDS, LVPECL, and crystal configurations. It utilizes a 40-VFQFN exposed pad package for surface mount applications.

Feature Summary

• Fourth-generation FemtoClock NG PLL technology
• Eight selectable LVPECL or LVDS outputs
• Flexible input support including HCSL, LVDS, LVPECL, and Crystal

Applications

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

Procurement Notes

Verify the specific suffix '063' against official Renesas documentation to confirm exact factory settings and configuration parameters. Ensure compatibility with required input/output voltage levels and signal standards before integration. Confirm RoHS compliance status through current datasheets.

Selection Notes

Select this component when precise jitter performance and multiple differential outputs are required. Consider the 40-VFQFN package constraints for PCB layout. Evaluate thermal requirements due to the exposed pad design. Verify that the 1.228GHz maximum frequency meets system timing needs.

Part Context

This part belongs to the FemtoClock NG family, designed for low-jitter clock generation in demanding digital environments. It replaces older generations with improved phase noise characteristics and flexible I/O configurations suitable for modern high-bandwidth interfaces.

Replacement Considerations

Check Renesas cross-reference guides for direct pin-compatible upgrades within the 8T49N008A series. Verify if alternative suffixes offer different pre-programmed frequencies or power modes without changing the physical footprint.
