Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct output type and tolerance. Confirm that the HCSL output variant matches the receiving circuit's input requirements. Check for any recent revisions to the mechanical dimensions or thermal specifications before finalizing the bill of materials.

Oscillators Selection Notes

Select this component when low jitter and robustness against mechanical stress are critical. The HCSL output is suitable for driving high-capacitance loads without additional buffering. Ensure the design accommodates the required pull range and that the 3V supply rail is stable within the specified operating temperature window.

Oscillators Part Context

This part belongs to the SiT3373 Elite Platform series, which offers programmable MEMS oscillators. The series supports frequencies from 220 MHz to 725 MHz. It replaces discrete crystal solutions by integrating the resonator and oscillator circuit into a single surface-mount package, reducing board space and assembly complexity.

Oscillators Replacement Considerations

Direct replacements must match the 432 MHz frequency, HCSL output, and 6-SMD footprint. Verify that substitute parts offer comparable jitter performance and pull range. Cross-reference pinouts to ensure electrical compatibility, as output swing levels may vary between manufacturers.
