Oscillators Procurement Notes

Verify the specific suffix OE against official Mercury Electronics documentation to confirm exact electrical characteristics and pinout configuration. Ensure the required frequency tolerance and load capacitance match the target circuit design requirements before procurement. Cross-reference the part number with authorized distributors to confirm current availability and authenticity.

Oscillators Selection Notes

Select this component when a precise 21.38 MHz clock source is required with low-voltage operation. The choice depends on the need for an enable/disable feature to manage power consumption or system states. Consider the physical footprint constraints of the 2.0x1.6mm package during PCB layout planning to ensure adequate spacing and thermal management.

Oscillators Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequency options within a standardized small outline package. The series supports multiple supply voltages and output types, allowing designers to maintain consistent mechanical footprints across different product lines while adjusting electrical specifications as needed.

Oscillators Replacement Considerations

Direct substitutes include other 21.38 MHz XO models from Mercury Electronics such as the 18QHTF21-21.380-PD, provided the package type and electrical parameters are identical. Verify that any replacement maintains the same LVCMOS output level and 1.8V supply requirement to ensure circuit compatibility.
