Procurement Notes

Verify the specific order code suffix against official Renesas documentation to confirm factory pre-programmed frequency configurations. Confirm package marking details and assembly site changes through Product Change Notifications (PCNs). Ensure compatibility with existing system voltage levels and thermal requirements before integration.

Selection Notes

Select this component when precise frequency translation from disparate input references is required. Evaluate the need for hitless switching and phase-slope limiting features for signal integrity. Compare against other FemtoClock NG variants based on the number of required output channels and specific jitter attenuation specifications.

Part Context

This part belongs to the FemtoClock NG family of timing devices designed for high-performance clock generation and distribution. These components are engineered to meet stringent jitter limits for high-speed serial applications. The series typically integrates programmable dividers and flexible input/output options for versatile system synchronization.

Replacement Considerations

Consult official substitution lists for compatible models such as the 8T49N241 series. Verify that alternative parts support the same input/output voltage levels and package footprint. Review datasheets for differences in register programming and feature sets.
