Procurement Notes
Verify the exact frequency tolerance and load capacitance requirements against your specific circuit design before procurement. Confirm that the 1.8V operating voltage aligns with your system's power rails. Ensure the 4-SMD package footprint matches your PCB layout constraints. Request the official datasheet from Mercury Electronics for precise electrical characteristics and reliability data.
Selection Notes
Select this component when a stable 7.20375 MHz reference is required for LVCMOS-compatible digital interfaces. Consider the enable/disable feature if power management during idle states is necessary. Evaluate the 1.8V operation against other available voltage options if your system uses different logic levels. Compare the 4-SMD form factor with space-constrained design alternatives.
Part Context
This part belongs to the 18QHTF21 series of standard crystal oscillators produced by Mercury Electronic. The series typically offers various frequency options within a standardized small outline package. Mercury Electronics specializes in quartz crystal and oscillator manufacturing, providing frequency control solutions for electronic applications.
Replacement Considerations
Direct substitutes must match the 7.20375 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD package. Verify pinout compatibility and electrical specifications with alternative manufacturers before substitution.
