Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your power management scheme. Ensure the 4-SMD footprint matches your PCB layout constraints to guarantee proper assembly and electrical connectivity.

Selection Notes

Choose this component when a low-voltage, small-footprint oscillator with control capabilities is required. It is suitable for designs needing a 71.25 MHz reference. Consider thermal performance and board space limitations. Verify compatibility with downstream logic levels to ensure signal integrity across operating conditions.

Part Context

This part belongs to the 18QHTF series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies and voltages. The 'OE' suffix indicates the presence of an enable pin. This model specifically targets the 71.25 MHz niche within the broader portfolio of quartz-based timing solutions.

Replacement Considerations

Check datasheets for compatible parts offering identical 71.25 MHz frequency, 1.8V operation, and LVCMOS output. Ensure pinout compatibility for the 4-SMD package. Verify that substitute components meet the same enable/disable functional requirements and physical dimensions.
