Procurement Notes

Verify the specific package outline dimensions and pin assignment against the official IQD datasheet before PCB layout finalization. Confirm that the target application logic levels are compatible with the CMOS output swing characteristics. Ensure the design accounts for the enable/disable control signal requirements during operation.

Selection Notes

Select this component when a 40 MHz reference is required alongside power-saving capabilities. The CMOS output interface suits direct connection to standard logic families. Consider the 4-pin SMD footprint constraints and thermal dissipation needs relative to the surrounding board components.

Part Context

This part belongs to the LFSPXO series of standard oscillators from IQD Frequency Products. These devices are designed to replace discrete crystal and resonator solutions by providing a ready-to-use clock signal. The series emphasizes reliability and ease of integration into modern electronic assemblies.

Replacement Considerations

Direct substitutes include other 40 MHz CMOS oscillators in identical 4-SMD packages with matching voltage ranges. Verify electrical parameters such as load capacitance and stability specifications to ensure functional equivalence in the existing circuit design.
