Procurement Notes

Verify the specific package height variant during procurement, as documentation indicates a 1.8 mm profile for this part number, which differs from other series variants. Confirm the exact supply voltage requirements against the target circuit design to ensure compatibility with the specified 3.3 V nominal operation. Cross-reference the manufacturer's latest datasheet to confirm current production status and any potential pinout or parameter updates.

Selection Notes

Select this component when a 40 MHz reference is required for applications operating between 0°C and +70°C. Ensure the system power rail aligns with the 3.3 V specification. Consider the physical dimensions of 7.2 x 5.2 x 1.8 mm for PCB layout constraints. Verify that the load capacitance requirements of the connected circuitry are compatible with the oscillator's internal configuration.

Part Context

This oscillator belongs to the LFSPXO family of standard clock oscillators manufactured by IQD Frequency Products. These components are designed to replace discrete crystal and resonator circuits by providing a ready-to-use clock signal.
