Oscillators Procurement Notes

Verify the specific suffix (OE vs PD) against the manufacturer's official datasheet to confirm exact electrical tolerances and pinout configurations. Ensure the 1.8V supply requirement aligns with the target circuit design. Confirm package dimensions match PCB footprint constraints before finalizing procurement.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a small 2016 SMD footprint. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the enable feature if power management during idle states is necessary for the application.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequency options within a standardized 2.0x1.6mm package. These oscillators are designed to replace discrete crystal and resonator circuits, providing a ready-made clock source with stable performance.

Oscillators Replacement Considerations

Check for direct substitutes such as the 18QHTF21-38.900-PD variant, ensuring voltage and package compatibility. Verify that alternative sources offer identical LVCMOS outputs and 1.8V operation to maintain circuit integrity without redesign.
