Procurement Notes

This product is listed as discontinued by the manufacturer. Verification of availability through authorized distributors or surplus channels is required. Check for relevant Product Change Notices (PCN) regarding end-of-life status or alternative sourcing options before procurement planning.

Selection Notes

Select this component when a single differential input must be distributed to four LVPECL loads at frequencies up to 300MHz. Ensure the design accommodates the 32-VFQFN package thermal requirements. Verify that the input signal levels match the supported HCSL, LVDS, or LVPECL specifications.

Part Context

The 8T49N008A-058NLGI8 belongs to the FemtoClock NG family, which utilizes fourth-generation PLL technology for low phase jitter performance. It is part of the broader 8T49N008 series, differentiated by specific output configurations and programming codes defined by the order code suffix.

Replacement Considerations

As the part is discontinued, consult Renesas documentation for officially confirmed substitute part numbers. Generic equivalents are not verified; only cross-references explicitly stated in official replacement notices should be considered.
