8T49N004A-062NLGI

Overview

The Renesas 8T49N004A-062NLGI is a programmable clock generator from the FemtoClock NG series. It features a single PLL circuit with a 1:4 input-to-output ratio, supporting crystal inputs and LVDS/LVPECL differential outputs. The device operates within a supply voltage range of 2.375V to 3.465V and supports maximum frequencies up to 500MHz. Packaged in a 32-VFQFN (5x5mm) exposed pad for surface mount installation, it functions reliably across an industrial temperature range of -40°C to 85°C.

Procurement Notes

Verify component status as this model may be discontinued or subject to product change notices. Confirm RoHS3 compliance and moisture sensitivity level (MSL 3) prior to procurement. Check for valid datasheets and PCNs to ensure design continuity and manufacturing compatibility.

Selection Notes

Select this component when a single PLL with four differential outputs is required. Ensure the application supports crystal input configurations and LVDS/LVPECL load requirements. Verify that the 32-VFQFN footprint matches the PCB layout constraints and thermal management needs.

Part Context

This part belongs to the Renesas FemtoClock NG family, designed for low-jitter clock generation. It shares architectural similarities with other 8T49N004 variants but differs in specific output configurations and packaging options. The 8T49N004A-062NLGI specifically targets applications requiring robust differential signaling capabilities.

Replacement Considerations

Consult official substitution guides for compatible alternatives. Verify pinout compatibility and electrical parameter equivalence before replacing. Consider package dimensions and thermal characteristics to ensure seamless integration into existing designs.
