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 Enable/Disable pin configuration matches the host controller's GPIO capabilities to utilize the power-saving feature effectively.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling. The Enable/Disable feature makes it suitable for battery-powered devices where power efficiency during idle states is critical. Consider the small form factor of the 4-SMD package for space-constrained layouts.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and voltage options, with the OE suffix typically indicating specific enable/disable configurations or packaging variants within the manufacturer's catalog.

Oscillators Replacement Considerations

Direct substitutes include other 1.8V LVCMOS oscillators in 4-SMD packages with similar frequency ranges. Verify electrical parameters such as jitter and phase noise if strict timing precision is required. Check pinout compatibility to ensure seamless integration without PCB redesign.
