Procurement Notes

This component is officially discontinued by Renesas Electronics. Distributors such as Mouser indicate that sales are not available in certain regions. Engineers must verify the validity of existing stock through authorized channels and review Product Change Notifications (PCN) or End-of-Life notices for final disposition details before procurement attempts.

Selection Notes

Designers requiring active inventory should evaluate alternative parts from the same FemtoClock family. The 8T49N287 series offers similar frequency translation capabilities. Verify pin compatibility and electrical specifications against current production models to ensure seamless integration into existing designs without redesigning the PCB layout.

Part Context

The 8T49N287 series represents Renesas's fourth-generation FemtoClock technology designed for low jitter performance. These devices serve as universal frequency translators capable of accepting various input references and generating multiple output frequencies. The -999 suffix typically denotes specific factory pre-programmed configurations or power-up states defined by the order code.

Replacement Considerations

Public records list the 8T49N241 and 8T49N242 series as similar alternatives. These components share the FemtoClock NG platform but may differ in output count and specific jitter performance metrics. Validate functional equivalence through detailed datasheet comparison.
