LFSPXO082158

Overview

The LFSPXO082158 is a standard crystal oscillator from IQD Frequency Products, operating at a nominal frequency of 50 MHz with a frequency stability of ±25 ppm. It features a CMOS output format and operates within a supply voltage range of 3.3 V. The component is housed in a compact 4-SMD, No Lead package measuring 2 mm x 1.6 mm. It supports an operating temperature range starting from -20°C, suitable for various electronic applications requiring precise timing signals.

Feature Summary

• Compact surface-mount design for space-constrained PCB layouts
• CMOS output interface for direct logic integration
• Standard frequency stability for general timing requirements

Applications

• General-purpose digital circuit timing
• Microcontroller clock sources
• Consumer electronics internal synchronization

Procurement Notes

Verify the specific operating temperature lower limit, as sources indicate -20°C while other IQD series start at -40°C. Confirm package dimensions match the 2mm x 1.6mm specification. Ensure the CMOS output level compatibility with the target system logic voltage before finalizing the procurement order.

Selection Notes

Select this model when a small footprint is critical and CMOS output is required. Compare against the LFSPXO-540 series for potentially wider industrial temperature ranges if -20°C is insufficient. Verify that the 50 MHz frequency aligns with system clock requirements and that ±25 ppm stability meets jitter tolerance limits.

Part Context

This part belongs to the IQD Frequency Products standard oscillator portfolio, which includes various SMD and THT options. The LFSPXO series typically offers low-cost solutions for IoT and general electronics. It complements larger packages like the 7x5mm LFSPXO variants by providing a miniature alternative for high-density designs.

Replacement Considerations

Check for alternate part numbers or revision changes indicated in manufacturer documentation. Direct substitutes may include other 50MHz CMOS oscillators in 2x1.6mm packages from IQD or competitors, provided pinout and electrical parameters are identical.
