Oscillators Procurement Notes

Verify the specific frequency tolerance and stability requirements against your system design before procurement. Ensure the 1.8V supply voltage aligns with your power management architecture. Confirm that the LVCMOS output swing meets the input threshold specifications of the receiving logic. Check for any specific handling instructions related to the lead-free soldering process for the SMD package.

Oscillators Selection Notes

Select this oscillator when a 37.152 MHz reference is required with minimal power draw. Consider the 1.8V supply constraint and LVCMOS interface compatibility. Evaluate the physical size constraints imposed by the 4-SMD package. Compare alternative frequencies if the exact 37.152 MHz value does not match the target application's timing needs.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on low-voltage crystal oscillators. The series typically includes various frequencies and output types, all sharing similar power-saving features and compact packaging. The 'PD' suffix indicates the inclusion of a power-down control function, distinguishing it from standard continuous-operation variants within the same family.

Oscillators Replacement Considerations

Direct substitutes must match the 37.152 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering equivalent low-power XO components.
