Procurement Notes

Verify the specific suffix (e.g., MBM) against official QST documentation to confirm exact electrical parameters such as frequency tolerance and temperature range. Ensure the component matches the required package type and RoHS compliance status. Cross-reference datasheet specifications with project requirements before finalizing procurement orders.

Selection Notes

Select this oscillator when EMI certification challenges arise in high-speed digital interfaces. The built-in phase modulation feature allows hardware-level EMI reduction without changing circuit topology. Consider the wide operating temperature range for industrial or automotive applications where thermal stability is critical for clock accuracy.

Part Context

The QTM216E series represents QST's solution for low EMI clock generation in compact form factors. This model specifically targets applications requiring precise timing with minimal radiated emissions. The integration of EMI reduction capabilities directly into the oscillator package simplifies design processes compared to traditional crystal oscillator solutions.

Replacement Considerations
