Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions to avoid assembly issues. Check for RoHS compliance status if required by your manufacturing standards.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS interface. The small 2.0x1.6mm package makes it suitable for space-constrained designs. Consider the enable/disable feature if power management during idle states is a priority. Verify that the 24.9975 MHz frequency meets the exact timing needs of the target application.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a standardized 1.8V LVCMOS format. The series provides consistent packaging and electrical characteristics across different frequency options, allowing for easier inventory management and design reuse across multiple product lines.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series parts with compatible frequencies such as 18QHTF21-25.0000-OE if frequency adjustment is acceptable. Cross-reference with similar 1.8V LVCMOS oscillators in the same 2.0x1.6mm package from other manufacturers, ensuring pinout and electrical specifications match.
