Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD No Lead package footprint matches your PCB layout constraints. Check for any RoHS compliance documentation if required by your manufacturing standards.

Oscillators Selection Notes

Select this component when a precise 16.54111 MHz reference is needed in space-constrained designs. The 1.8V operation makes it suitable for modern low-voltage digital logic families. The integrated standby feature allows for power optimization in battery-operated equipment. Consider the small 2.0x1.6mm footprint for high-density board layouts.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequencies within the same compact form factor. The 'PD' suffix indicates the inclusion of a power-down pin or function, distinguishing it from continuous-output variants in the same family.

Oscillators Replacement Considerations

Direct substitutes may include other 16.54111 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pin compatibility and electrical specifications before swapping. Cross-reference with similar Mercury Electronics models like the 18QHTF21-18.1059-PD for dimensional compatibility, though frequencies differ.
