Oscillators Procurement Notes

Verify the specific suffix (OE) against official Mercury Electronics documentation to confirm the presence of the enable pin and LVCMOS output characteristics. Ensure the operating temperature range and load capacitance requirements align with the target application design specifications before procurement.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside precise frequency stability. The small 2.0x1.6 mm footprint makes it suitable for space-constrained designs. Confirm that the LVCMOS output swing matches the input voltage thresholds of the receiving logic gates.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which provides standard quartz crystal oscillators. The manufacturer specializes in frequency control products including crystals, TCXOs, and VCTCXOs, offering various package sizes and output types for diverse electronic applications.

Oscillators Replacement Considerations

Check for direct substitutes such as the 18QHTF21-25.126-PD variant from the same manufacturer, ensuring pinout and electrical parameters match. Cross-reference with other LVCMOS oscillators of identical frequency and voltage if availability is an issue.
