Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply rail stability meets the oscillator's specifications to maintain signal integrity. Confirm that the PCB footprint matches the 4-SMD no-lead package dimensions provided in the official datasheet to avoid assembly issues during manufacturing.

Oscillators Selection Notes

Select this component when a low-profile, low-voltage oscillator with standby capability is required. The 1.8V operation makes it suitable for modern low-power digital circuits. Consider the 2.0x1.6mm package size for space-constrained designs. Verify that the LVCMOS output level aligns with the input voltage thresholds of the connected microcontroller or FPGA.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on small-form-factor crystal oscillators. The series typically offers various frequencies and voltage options. The 'PD' suffix indicates the inclusion of a power-down feature. This model specifically targets applications needing a balance between size, power consumption, and timing accuracy in portable devices.

Oscillators Replacement Considerations

Direct substitutes within the same series include other frequency variants such as 18QHTF21-51.200-PD or 18QHTF21-3.276-PD, provided the frequency difference is acceptable for the application. Cross-brand replacements must match the 1.8V supply, LVCMOS output, and 4-SMD no-lead package dimensions.
