Procurement Notes

Verify the specific part number revision when ordering, as the manufacturer has updated the part number designation for this component. Confirm that the required packaging format aligns with production needs, as availability may vary by region. Ensure compatibility with the target circuit's voltage and load requirements before finalizing procurement decisions.

Selection Notes

Select this component when a precise 32.768 kHz reference is required in a minimal footprint. The 50 ppm stability suits general timing applications rather than high-precision metrology. Consider the 3.3 V supply constraint and ensure the host system provides adequate current. The small 1.6x1.2 mm package is ideal for portable or dense electronics where board real estate is limited.

Part Context

This oscillator belongs to the IQXO-984 series, which focuses on low-frequency standard oscillators. The series emphasizes miniaturization while maintaining reliable performance across industrial temperature ranges. It serves as a dedicated timing solution for applications requiring stable sub-MHz frequencies in modern surface-mount designs.

Replacement Considerations

Check for official part number revisions issued by the manufacturer, as previous designations may have been updated. Verify pinout and electrical specifications against potential substitutes to ensure functional equivalence without redesigning the host circuit.
