Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm exact electrical tolerances and packaging configurations. Ensure the selected variant matches the required operating temperature range and supply voltage specifications for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when a 16MHz reference signal with moderate stability is required for embedded systems. The enable pin feature makes it suitable for applications requiring power conservation during idle states. Verify that the load capacitance requirements of the connected circuitry align with the oscillator's specified output drive capabilities to ensure signal integrity.

Part Context

This part belongs to the CFPS-73 series of standard oscillators manufactured by IQD Frequency Products. The series offers various frequencies and stability options in compact surface-mount packages. The LFSPXO018038 specifically targets general-purpose timing needs where size constraints and basic jitter performance are balanced with cost-effectiveness.

Replacement Considerations

Cross-reference with other 16MHz HCMOS oscillators in the 7x5mm package. Verify pinout compatibility and electrical parameters such as supply voltage and output swing before substitution.

FAQ

How is the enable/disable function controlled?

Pin 1 controls the state; connecting it high or leaving it floating enables normal operation, while connecting it low disables the output.

What is the typical standby current?

The standby current is approximately 10μA when the output is disabled.
