• Embedded controllers needing low-voltage clock sources

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system's power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this oscillator when a standard LVCMOS output is required alongside a 1.8V operating voltage. The choice is appropriate for applications prioritizing a small 2.0x1.6 mm form factor. Consider the power-down feature if dynamic power management is necessary. Validate that the 14.745 MHz frequency meets the system's timing constraints without additional dividers or multipliers.

Oscillators Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of surface-mount oscillators. The series is characterized by its small footprint and low voltage operation. Mercury Electronics has extensive experience in quartz crystal manufacturing, positioning this component within a lineage of established frequency control products designed for modern electronic devices.

Oscillators Replacement Considerations

Direct substitutes include other 14.745 MHz LVCMOS oscillators in 4-SMD packages from compatible manufacturers. Verify pinout compatibility and electrical parameters such as supply voltage and output swing. Alternative models like the 18QHTF21-51.200-PD differ only in frequency and are not electrically interchangeable.
