Procurement Notes

Verify the specific part number against official manufacturer documentation to ensure compatibility with system requirements. Confirm that the operating voltage and frequency stability meet the design specifications. Check for any required environmental certifications or compliance standards relevant to the target application before finalizing procurement decisions.

Selection Notes

Select this component when a 20 MHz clock source is required in a small form factor. Ensure the circuit design accommodates the 3.3V supply requirement and the ±50 ppm frequency tolerance. Consider the -40°C to +85°C operating range to verify suitability for the intended environmental conditions during product development.

Part Context

This oscillator belongs to the QTM325 series, which provides various frequency options in a standardized 3.2 x 2.5 mm package. The series is designed for general-purpose timing applications where size and power efficiency are critical factors. Other variants in the family offer different frequencies while maintaining similar physical and electrical characteristics.

Replacement Considerations

Direct substitutes may include other 20 MHz oscillators in the same 3.2 x 2.5 mm package with compatible voltage and stability ratings. Verify pinout compatibility and load capacitance requirements before replacing the original component with an alternative supplier's part.
