Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design specifications before procurement. Ensure that the 1.8V supply voltage aligns with your system's power rails. Confirm that the 4-SMD package footprint matches your PCB layout constraints. Check for any specific operating temperature range limitations required by your application environment. Validate that the LVCMOS output levels are compatible with the receiving logic inputs.

Oscillators Selection Notes

Select this component when a low-profile 2.0x1.6 mm oscillator is required for 37.1249 MHz applications. Consider the 1.8V supply requirement and LVCMOS output compatibility with your target logic family. Evaluate the need for a standby feature to manage power efficiency in portable or battery-operated devices. Compare the physical dimensions against available board space to ensure proper fitment within the enclosure design.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic Ind. Co. Ltd, which offers various frequencies within a standardized 4-SMD package. The series provides options for different clock speeds while maintaining consistent physical dimensions and electrical characteristics. The 'PD' suffix indicates the inclusion of a power-down capability, distinguishing it from non-stby variants in the same form factor.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series oscillators with identical 2.0x1.6 mm packages and 1.8V operation, such as the 18QHTF21-50.000-PD or 18QHTF21-8.000-PD, provided the frequency difference is acceptable for the application.
