Procurement Notes

Verify the specific suffix METC-T against official QST documentation to confirm exact electrical parameters and packaging details. Ensure compatibility with your PCB footprint and reflow soldering profile. Cross-reference the datasheet for absolute maximum ratings and recommended operating conditions before integration into final designs.

Selection Notes

Select this component when a 54 MHz clock source is required with tight frequency accuracy. The ±10 ppm specification suits applications sensitive to timing drift. Consider the 2x1.6mm footprint for dense layouts. Evaluate thermal requirements against the -30°C to +85°C range to ensure suitability for the intended environmental conditions.

Part Context

This part belongs to the QT216S series of quartz crystal oscillators from QST. The series offers various frequencies and stability options in a standardized small outline package. These components are commonly used as timing references in digital logic, microcontrollers, and communication interfaces where stable clock generation is critical for system synchronization.

Replacement Considerations

Direct substitutes include other 54 MHz crystals with identical ±10 ppm stability and 4-SMD no-lead packages. Verify pinout compatibility and load capacitance requirements. Check if alternative manufacturers offer equivalent performance metrics within the same physical dimensions.
