LFSPXO018045

Overview

The LFSPXO018045 is a standard clock oscillator from the IQD CFPS-73 series, operating at a nominal frequency of 8 MHz. It features a 7 mm x 5 mm surface-mount package with dimensions of 7.2 mm length, 5.2 mm width, and 1.4 mm height. The device provides 50 ppm frequency stability and supports an HCMOS output format. It operates within a supply voltage range of 2.97 V to 3.63 V, with a typical load capacitance of 50 pF. The component is rated for an industrial temperature range of 0°C to +70°C.

Feature Summary

• Hermetically sealed construction using a ceramic body and seam-sealed metal lid for environmental protection
• HCMOS output interface compatible with standard digital logic circuits
• Industrial temperature grade operation suitable for demanding environments

Applications

• Clock and timing distribution systems
• Aerospace electronic equipment
• Defense communication hardware

Procurement Notes

Verify the specific suffix (e.g., Reel) against the required packaging configuration. Confirm that the 50 ppm stability and 0°C to +70°C temperature range meet the system requirements. Ensure the 7x5mm footprint matches the PCB design constraints before finalizing the order.

Selection Notes

Select this model when hermetic sealing is required for reliability in harsh environments. The 8 MHz frequency and HCMOS output are fixed specifications. Consider the 50 ppm stability limit and the specific voltage range of 2.97V to 3.63V during circuit design to ensure proper operation under all conditions.

Part Context

This part belongs to the IQD CFPS-73 series of standard crystal oscillators. The series offers various frequencies and stability options in a compact 7x5mm package. The LFSPXO018045 specifically targets applications requiring hermetic sealing and industrial temperature performance.

Replacement Considerations

Check for alternate part numbers listed by distributors, such as those with different suffixes indicating packaging changes. Verify that any substitute maintains the same hermetic seal specification and electrical parameters.
