Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Confirm that the 4-SMD package dimensions align with your PCB footprint. Ensure the CMOS output voltage levels are compatible with the receiving logic family. Check for RoHS compliance documentation if required by your manufacturing standards.

Oscillators Selection Notes

Select this component when low EMI is critical for signal integrity in high-frequency digital systems. The spread spectrum feature helps meet regulatory emissions standards without additional filtering. The enable pin allows for dynamic power saving in battery-operated or thermally constrained environments. Ensure the operating temperature range meets the application's environmental specifications.

Oscillators Part Context

This oscillator belongs to the QHM series of spread spectrum crystal oscillators from Mercury Electronics. The series is characterized by its ability to modulate the output frequency slightly to reduce peak spectral energy. This model specifically targets applications needing precise timing with minimized noise impact on sensitive analog or RF sections of the circuit.

Oscillators Replacement Considerations

Direct replacements must match the 20.025 MHz frequency, CMOS output, and 4-SMD package. Verify that substitute parts support the same enable/disable functionality and spread spectrum characteristics. Cross-reference electrical parameters such as phase noise and jitter to ensure performance parity.
