LFSPXO071237

Overview

The LFSPXO071237 is a standard CMOS clock oscillator manufactured by IQD Frequency Products. It operates at a nominal frequency of 40 MHz with a frequency stability of ±100 ppm. The device supports a supply voltage range from 1.8 V to 3.63 V and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package measuring 3.2 mm x 2.5 mm x 0.8 mm. The component is designed for surface mount technology (SMD) applications.

Feature Summary

• Integrated enable and disable functionality for power management
• CMOS output format compatible with digital logic circuits
• Compact 4-SMD no-lead surface mount package design

Applications

• General purpose timing reference for embedded systems

Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the official datasheet before procurement. Confirm that the selected package variant matches the PCB footprint dimensions of 3.2 mm x 2.5 mm. Ensure the supply voltage provided aligns with the specified operational limits to guarantee stable oscillation and longevity of the component.

Selection Notes

Select this oscillator when a low-profile surface mount solution is required for 40 MHz timing applications. Consider the ±100 ppm stability specification for general digital logic synchronization. Evaluate the enable/disable feature if system-level power conservation is a priority. Compare physical dimensions against available board space constraints prior to finalizing the design.
