Oscillators Procurement Notes

Verify the exact frequency tolerance and load capacitance requirements against your specific design needs before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD package footprint matches your PCB layout constraints. Cross-reference the manufacturer part number to avoid confusion with similar variants in the 18QHTF21 series.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling levels. The integrated enable pin makes it suitable for battery-powered or power-sensitive designs. Consider the small form factor if space constraints are critical. Verify that the 18.869 MHz frequency meets the system's timing specifications without requiring external dividers or multipliers.

Oscillators Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystal products. The company has decades of experience in frequency control manufacturing. This specific model represents a standard XO variant designed for general-purpose timing applications where size and power consumption are key considerations.

Oscillators Replacement Considerations

Direct substitutes within the same series include other frequencies such as 18QHTF21-18.8686-OE or 18QHTF21-44.200-OE if frequency adjustment is acceptable. Ensure any replacement maintains the 1.8V supply and LVCMOS output characteristics. Verify package compatibility before swapping.
