Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the 4-SMD package footprint matches the PCB layout specifications to guarantee proper assembly and electrical connectivity.

Oscillators Selection Notes

Select this component when a precise 18.1059 MHz reference is required for low-voltage digital systems. The integrated enable pin allows for dynamic power control, making it suitable for battery-operated devices. Consider the small form factor for space-constrained applications requiring reliable timing signals without external buffering.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options, all sharing a common compact package style. The suffix OE indicates the presence of an enable/disable control feature, distinguishing it from standard continuous-output variants within the same family.

Oscillators Replacement Considerations

Direct substitutes must match the 18.1059 MHz frequency, 1.8V operation, LVCMOS output, and 4-SMD package dimensions. Verify equivalent enable functionality and electrical characteristics. Cross-reference with other manufacturers offering similar SMD oscillators if availability is constrained.
