LFSPXO056221

Overview

The LFSPXO056221 is a standard crystal oscillator from the IQXO-542 series manufactured by IQD Frequency Products. It operates at a nominal frequency of 40 MHz with a frequency stability of ±50 ppm across an operating temperature range of -40°C to +85°C. The device utilizes CMOS output format and is designed for surface-mount applications in a compact 2.0 mm x 1.6 mm x 0.7 mm package. It supports a supply voltage range typically centered around 1.8V, featuring low power consumption suitable for portable electronics.

Feature Summary

• Compact ceramic package with seam-sealed metal lid
• CMOS output interface for digital logic compatibility
• Low power operation optimized for battery-powered devices
• Integrated enable/disable functionality

Applications

• Portable consumer electronics
• Mobile communication devices
• Embedded systems requiring precise timing
• Battery-operated instrumentation

Procurement Notes

Verify the specific supply voltage requirements against the official datasheet, as variants may exist within the series. Confirm RoHS compliance status and lead-free specifications prior to integration. Ensure the ordering suffix matches the required packaging type, such as cut tape or reel, to align with assembly processes. Cross-reference the part number with the manufacturer's latest documentation to confirm current production status and availability.

Selection Notes

Select this component when a small form factor is critical for PCB layout constraints. The CMOS output is appropriate for direct interfacing with digital processors without additional buffering. Consider the ±50 ppm stability sufficient for general clocking needs but verify if tighter tolerance is required for high-speed serial interfaces. Evaluate the 1.8V supply requirement against the system's available power rails.

Part Context

This oscillator belongs to the IQXO-542 series, which focuses on miniaturization and low power consumption. It serves as a timebase solution for applications where space is limited and energy efficiency is prioritized. The series is designed to replace larger through-hole or standard SMD oscillators in modern compact electronic designs.

Replacement Considerations

Direct substitutes include other 40 MHz CMOS oscillators in 2x1.6mm packages from compatible manufacturers. Verify pinout compatibility and electrical parameters before substitution. Generic replacements must match the supply voltage and output drive strength.
