• Industrial control boards needing reliable clock sources

Procurement Notes

Verify the specific suffix 'MDJ' against official QST documentation to confirm pinout configuration and tape-and-reel specifications. Ensure that the 1.8V supply requirement aligns with the target circuit design before procurement. Cross-reference the ±50ppm stability rating with system timing tolerances to prevent synchronization errors in high-speed data interfaces.

Selection Notes

Select this component when a low-profile, 1.8V CMOS oscillator is required for 12 MHz applications. Consider the ±50ppm stability limit for timing-sensitive circuits. Evaluate the 2mm x 1.6mm package size against available PCB real estate. Confirm compatibility with the target operating temperature range of -40°C to +85°C for environmental resilience.

Part Context

This part belongs to the QTM216J series of ultra-miniature oscillators from QST. The series is characterized by small footprints and low power consumption, targeting portable and embedded devices. The QTM216J variant specifically integrates CMOS outputs, distinguishing it from other series members that may offer different output types or voltage levels.

Replacement Considerations

Direct substitutes include the QTM216J-12.000MDE-T and QTM216J-12.000MBE-T, provided they match the 1.8V supply and CMOS output requirements. Verify package dimensions and pin assignments before substitution to ensure mechanical and electrical compatibility.
