LFSPXO018037

Overview

The LFSPXO018037 is a standard crystal oscillator from the CFPS-73 series, manufactured by IQD Frequency Products. It operates at a nominal frequency of 12 MHz with a frequency stability of ±50 ppm. The device utilizes an HCMOS output format and is powered by a single supply voltage ranging from 2.97 V to 3.63 V, typically centered at 3.3 V. It features a hermetically sealed ceramic package with a seam-welded metal lid, measuring 7 mm in length, 5 mm in width, and 1.4 mm in height. The component supports a load capacitance of up to 50 pF and includes an enable/disable function for power management.

Feature Summary

• Hermetically sealed construction using a seam-welded metal lid on a ceramic substrate for enhanced environmental protection against dust and moisture.
• Integrated enable/disable functionality allowing the output to enter a high-impedance state, significantly reducing current consumption during inactive periods.
• HCMOS logic-compatible output signal providing standard drive capabilities suitable for direct interfacing with microcontrollers and digital circuits.

Applications

• Clock and timing sources for industrial data acquisition gateways
• Master clock generation for microcontroller units (MCUs) in embedded systems
• Timing references for industrial communication interfaces requiring stable frequency
• Aerospace, defense, and military electronic equipment demanding high reliability

Procurement Notes

Verify the specific order code suffix to confirm the exact packaging configuration, such as tape and reel or bulk quantities, as these may vary by distributor. Ensure that the selected variant matches the required operating temperature range and frequency tolerance specifications for the target application environment. Cross-reference the manufacturer's latest datasheet to confirm compliance with RoHS and REACH directives before finalizing procurement decisions.

Selection Notes

Select this component when a hermetically sealed oscillator is required for harsh environments where plastic packages may fail. The 7x5mm form factor offers a balance between size and robustness. Consider the enable pin feature if system power efficiency is critical. Verify that the HCMOS output voltage levels are compatible with the downstream logic family. Ensure the 12 MHz frequency aligns with the system clock requirements without needing external dividers or multipliers.

Part Context

The LFSPXO018037 belongs to the CFPS-73 series of standard crystal oscillators from IQD Frequency Products. This series is characterized by its use of ceramic packages with metal lids, designed for high reliability applications. The part number indicates a 12 MHz frequency option within this lineup, which is commonly used in general-purpose digital systems. The series supports various frequencies and stability grades, catering to diverse timing needs in industrial and commercial sectors.

Replacement Considerations

Direct substitutes must match the 7x5mm footprint, 12 MHz frequency, ±50 ppm stability, and HCMOS output. Check for equivalent hermetic sealing and enable functions. Verify supply voltage compatibility (3.3V typical). Consult manufacturer cross-reference guides for confirmed alternative part numbers with identical electrical and mechanical specifications.
