Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 3.3V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 3.2x2.5mm SMD package dimensions to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a low-frequency, stable clock source is required for digital logic interfaces. The LVCMOS output ensures compatibility with standard CMOS logic families. Consider the power-down feature if battery life or thermal management is a critical constraint in the final product design compared to non-stoppable oscillators.

Oscillators Part Context

This part belongs to the 3QHTF32 series from Mercury Electronics, which specializes in quartz crystal components. The series offers various frequencies within a standardized small form factor. The 'PD' suffix typically indicates the packaging style or specific handling configuration provided by the manufacturer for distribution purposes.

Oscillators Replacement Considerations

Direct substitutes must match the 1.44 MHz frequency, LVCMOS output type, 3.3V operating voltage, and 3.2x2.5mm package size. Verify pinout compatibility and electrical characteristics such as drive level and load capacitance to ensure functional equivalence in the existing circuit layout.
