LFSPXO056237

Overview

The LFSPXO056237 is a standard clock oscillator from the IQXO-540 series manufactured by IQD Frequency Products. It operates at a nominal frequency of 12 MHz with a stability of ±50 ppm. The device supports a supply voltage range of 2.97 V to 3.63 V and features a CMOS output format. It is housed in a compact 4-SMD, no-lead package measuring 2.0 mm x 1.6 mm x 0.7 mm. The component is designed for surface mount installation and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Hermetically sealed ceramic package with a seam-sealed metal lid
• Integrated enable/disable functionality for power management
• CMOS output signal format suitable for digital logic interfaces

Applications

• General purpose clock generation for embedded systems
• Timing reference for microcontrollers and processors
• Communication interface synchronization circuits

Procurement Notes

Verify the specific packaging configuration required for production, as the component is available in cut tape or reel formats. Confirm that the selected variant matches the exact 12 MHz frequency and 3.3 V nominal supply voltage requirements. Ensure the footprint corresponds to the 2.0 mm x 1.6 mm SMD dimensions to guarantee proper PCB integration and mechanical fit during assembly.

Selection Notes

Select this oscillator when a small form factor is critical for space-constrained designs. The CMOS output is appropriate for direct interfacing with standard digital logic families. Consider the ±50 ppm stability specification against system timing tolerance requirements. The wide operating temperature range ensures reliability in industrial environments without requiring additional thermal compensation.

Part Context

This component belongs to the IQXO-540 series of standard crystal oscillators. The series offers various frequencies and package sizes optimized for high-volume consumer and industrial electronics. The LFSPXO056237 specifically utilizes a ceramic construction to provide hermetic sealing, distinguishing it from lower-cost epoxy-sealed alternatives while maintaining a low profile for modern surface-mount applications.

Replacement Considerations

Direct substitutes must match the 12 MHz frequency, 3.3 V supply, and 2.0x1.6mm footprint. Verify pin compatibility and output drive strength before swapping. Alternative packages may require schematic and layout modifications.
