Pin ConfigurableSelectable Oscillators Procurement Notes

This component is officially designated as Not Recommended for New Design (NRND) by Skyworks Solutions Inc. Procurement should focus on verifying current stock availability through authorized distributors rather than placing new manufacturing orders. Buyers must confirm lead times carefully, as production may be limited or discontinued. Ensure that any acquired units are genuine and match the specific suffix requirements for voltage and packaging before integration into final assemblies.

Pin ConfigurableSelectable Oscillators Selection Notes

Engineers selecting this part should consider its NRND status when planning long-term product lifecycles. While the Si549 series offers robust programmability and wide frequency coverage, newer Skyworks oscillators may provide improved performance or availability. Verify that the specific I2C address and pinout compatibility meet the target board design constraints. Review the datasheet for detailed electrical characteristics to ensure the selected frequency and load capacitance align with the system's timing requirements.
