LFSPXO025558

Overview

The LFSPXO025558 is a surface-mount crystal oscillator from the CFPS-39 series by IQD Frequency Products. It operates at a nominal frequency of 24 MHz with a stability of ±50 ppm. The device features a hermetically sealed ceramic package with a seam-sealed metal lid, housed in a compact 3.2 x 2.5 mm SMD footprint. It requires a nominal supply voltage of 3.3 V, ranging from 2.97 V to 3.63 V. The oscillator supports CMOS output and includes an enable/disable control function. It is designed for operation across an extended temperature range of -40°C to +85°C.

Feature Summary

• Hermetically sealed construction using ceramic body and seam-sealed metal lid for enhanced environmental protection
• Integrated enable/disable functionality allowing power management through control input
• CMOS output signal compatible with standard digital logic interfaces
• Compact surface-mount package design suitable for space-constrained PCB layouts

Applications

• Clock generation for high-speed digital communication interfaces
• Timing reference for microcontrollers and processors requiring stable clock sources
• Network equipment and telecommunications infrastructure systems
• Industrial control systems operating in extended temperature environments

Procurement Notes

Verify the specific ordering identifier against manufacturer documentation to ensure correct configuration. Confirm that the required frequency stability and temperature range align with system specifications. Check for any specific handling requirements related to the hermetic seal during assembly processes. Ensure compatibility with reflow soldering profiles specified for the 3.2x2.5mm package type.

Selection Notes

Select this component when hermetic sealing is required for reliability in harsh environments. Consider the 24 MHz frequency and ±50 ppm stability for applications needing precise timing without oven-controlled accuracy. Evaluate the 3.3V supply requirement against available power rails. Assess the need for enable/disable control versus always-on operation based on system power constraints.

Part Context

This part belongs to the CFPS-39 series of crystal oscillators from IQD Frequency Products. The series offers various frequencies and packages, with this specific model providing a balance of hermetic sealing and small form factor. It targets applications where long-term stability and environmental resistance are critical, distinguishing it from non-hermetic alternatives in the same product line.

Replacement Considerations

Direct substitutes must match the 24 MHz frequency, 3.3V supply, and 3.2x2.5mm package. Verify if alternative manufacturers offer hermetically sealed options with similar stability. Cross-reference pinouts and enable/disable logic levels to ensure functional compatibility without circuit modification.
