Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.
Selection Notes
Select this component when a stable 10.446875 MHz reference is required for LVCMOS-compatible digital circuits. Consider the enable/disable feature if power efficiency is critical. Verify that the operating temperature range meets the environmental conditions of the intended application. Compare package dimensions against available board space constraints.
Part Context
This part belongs to the 18QHTF21 series of quartz crystal oscillators from Mercury Electronics. The series offers various frequencies within the standard XO category. These components are designed for general-purpose timing applications in consumer electronics and industrial equipment, providing reliable frequency stability in a small form factor.
Replacement Considerations
Direct substitutes must match the 10.446875 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD package. Check manufacturer datasheets for pin-to-pin compatible alternatives with identical electrical characteristics.
