LFSPXO020392

Overview

The LFSPXO020392 is a standard clock oscillator manufactured by IQD Frequency Products. It operates at a nominal frequency of 18.432 MHz with a frequency stability of 50 PPM. The device supports a supply voltage range from 2.97 V to 3.63 V, typically centered at 3.3 V. It features an HCMOS output format and includes an enable/disable control function. The component is housed in a 4-SMD, no-lead surface mount package designed for automated assembly processes.

Feature Summary

• Integrated enable and disable functionality for power management control
• HCMOS output signal compatibility for digital logic interfaces
• Surface-mount construction optimized for high-volume PCB assembly

Applications

• General-purpose digital clock generation in embedded systems
• Microcontroller and processor clock sources requiring precise timing
• Industrial control equipment utilizing standard CMOS logic levels

Procurement Notes

Verify the specific supply voltage tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the HCMOS output swing matches the input thresholds of the receiving logic devices. Ensure the enable pin configuration aligns with the system's power sequencing strategy to prevent unintended oscillation states during startup or shutdown phases.

Selection Notes

Select this component when a stable 18.432 MHz reference is required for 3.3V logic systems. The 50 PPM stability suits applications where moderate precision is sufficient. Consider the enable feature if dynamic power saving is necessary. Evaluate the 4-SMD footprint against available board space constraints compared to larger oscillator packages.

Part Context

This part belongs to the LFSPXO series of standard crystal oscillators from IQD Frequency Products. These components are designed to replace discrete crystal and oscillator circuits with a single integrated solution. The series offers various frequencies and voltages, providing designers with standardized options for timing needs across consumer and industrial electronics sectors.

Replacement Considerations

Direct substitutes must match the 18.432 MHz frequency, 3.3V operation, and HCMOS output. Verify pinout compatibility for the 4-SMD package. Check if alternative manufacturers offer equivalent enable/disable functionality and similar stability specifications.
