Oscillators Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to ensure correct voltage, package, and stability specifications. Confirm RoHS compliance status and lead time requirements directly with authorized distributors, as availability may vary by region. Ensure the selected variant matches the required operating temperature range and output format for the target application design.

Oscillators Selection Notes

Select this component when a compact SOT-753 footprint is required alongside precise 3.579545 MHz timing. Consider its MEMS construction for applications subject to mechanical stress where traditional quartz might fail. Evaluate the ±50 ppm stability against system jitter requirements and confirm power consumption fits within the 3.3V supply constraints of the host circuit.

Oscillators Part Context

This part belongs to the SiT2001 series of general-purpose MEMS oscillators from SiTime Corporation. The series utilizes proprietary TempFlat technology to maintain frequency stability across temperature ranges. It serves as a silicon-based replacement for traditional quartz crystal oscillators, offering improved supply chain stability and configurability.

Oscillators Replacement Considerations

Direct pin-to-pin replacements should be verified using the SiTime Cross Reference Tool. Ensure substitute parts match the SOT-753 package, 3.3V supply, and 3.579545 MHz frequency. Check that alternative MEMS oscillators support the same LVCMOS/HCMOS output swing and meet the ±50 ppm stability requirement.
