LFSPXO064157

Overview

The LFSPXO064157 is a surface-mount standard clock oscillator from the IQXO-791 series manufactured by IQD Frequency Products. It operates at a nominal frequency of 40 MHz with a frequency stability of 25 ppm. The device utilizes HCMOS output logic and requires a supply voltage range centered around 3.3 V. It is housed in a compact 2 mm x 16 mm package designed for automated assembly.

Feature Summary

• High-precision timing performance suitable for demanding applications
• Compact surface-mount packaging for space-constrained designs
• HCMOS output interface for direct digital integration

Applications

• General purpose timing circuits
• Digital system clock generation
• Embedded controller synchronization

Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the target application environment before procurement. Confirm that the 3.3V supply rail meets the minimum and maximum voltage specifications defined in the official datasheet to ensure stable oscillation. Ensure PCB layout guidelines for the 2mm x 16mm package are strictly followed to maintain signal integrity and mechanical reliability during reflow soldering processes.

Selection Notes

Select this component when a 40 MHz reference with 25 ppm stability is required in a slim profile form factor. Compare against other IQXO-791 variants if different frequencies or tighter stability margins are needed. Consider the HCMOS output drive capability relative to the input requirements of the downstream logic family to avoid level shifting issues.
