Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions to prevent assembly issues during manufacturing.

Oscillators Selection Notes

Select this component when a 15.995 MHz clock source is required with low voltage operation. Consider the enable pin requirement if power management or clock gating is necessary for the application. Evaluate the small form factor suitability for dense board layouts compared to larger oscillator packages.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on small-sized SMD oscillators. The series typically offers various frequencies and output types. The suffix OE indicates the enable feature variant within this product line, distinguishing it from standard continuous-output models.

Oscillators Replacement Considerations

Direct substitutes include other 15.995 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation and enable pins. Verify electrical compatibility and pinout alignment before swapping manufacturers.
