Procurement Notes

Verify the specific suffix 'MDJ' against official QST documentation to confirm the 1.8V supply requirement and package dimensions. Ensure that the operating temperature range specified in the manufacturer's datasheet aligns with your environmental constraints. Cross-reference the part number with authorized distributors to confirm authenticity and avoid counterfeit components.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard CMOS output. Consider the ±50ppm stability specification relative to your system's timing tolerance requirements. Evaluate the 15 pF load capacitance compatibility with your circuit design to ensure accurate frequency performance without external trimming.

Part Context

This model belongs to the QTM216J series of quartz crystal oscillators from QST. The series typically includes variants with different frequencies and supply voltages, such as 3.3V versions. The QTM216J line is engineered for reliable performance in portable and industrial applications where size and power efficiency are critical factors.

Replacement Considerations

Direct substitutes may include other 1.8432 MHz CMOS oscillators with identical pinouts and electrical specifications. Verify that any replacement matches the 1.8V supply voltage and ±50ppm stability to maintain system integrity. Check for equivalent package dimensions to ensure mechanical fit.
