Oscillators Procurement Notes

Verify the specific ordering suffixes against the manufacturer's official datasheet to ensure correct frequency tolerance and package variant. Confirm that the enable pin configuration matches the target system's logic levels. Request batch-specific calibration certificates if strict phase noise or jitter specifications are required for the application. Ensure the supplier provides traceability documentation compliant with industry standards.

Oscillators Selection Notes

Select this component when a precise 20.48 MHz reference is needed with low power consumption capabilities. The ±50ppm stability is adequate for general-purpose digital interfaces but may require tighter tolerances for high-speed serial links. Consider the thermal environment, as the -40°C to 85°C range covers most commercial and industrial applications. Evaluate the footprint constraints against the 4-SMD package dimensions to ensure mechanical fit on the PCB.

Oscillators Part Context

This oscillator belongs to the SX3M series from Shenzhen SCTF Electronics, designed for general-purpose timing applications. The series typically includes various frequencies and package options to support diverse electronic designs. As an active crystal oscillator, it replaces discrete resonator circuits, offering improved reliability and reduced board space compared to passive components.

Oscillators Replacement Considerations

Direct replacements must match the 20.48 MHz frequency, 3.3V supply, and 4-SMD package. Verify that substitute parts offer equal or better frequency stability and operate within the same temperature range. Check for compatible enable pin logic levels to ensure seamless integration without circuit modification.
