LFSPXO009582

Overview

The LFSPXO009582 is a standard CMOS crystal oscillator manufactured by IQD Frequency Products. It operates at a nominal frequency of 4 MHz with a frequency stability of +/- 50 ppm. The device supports a nominal supply voltage of 3.3 V and features a standby or power-down function. It is housed in a 4-SMD, no-lead package measuring 5 mm x 3.2 mm. The component is designed for surface mount technology and complies with RoHS standards.

Feature Summary

• Integrated standby and power-down functionality for energy management
• CMOS output format compatible with digital logic circuits
• Compact 4-SMD surface-mount package design

Applications

• General purpose clock signal generation
• Embedded system timing references
• Consumer electronics circuit boards

Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the official IQD datasheet before integration. Confirm that the 3.3V supply voltage aligns with the target circuit's power rails. Ensure the 4MHz frequency matches the system clock input specifications to avoid timing errors.

Selection Notes

Select this component when a low-cost, standard frequency solution is required for non-critical timing applications. The 50 ppm stability is suitable for general digital interfaces but may be insufficient for high-precision communication protocols. Consider the power-down feature if battery life optimization is a priority for the end product.

Part Context

This part belongs to the CFPS-69 series of standard oscillators from IQD Frequency Products. The series provides economical quartz-based timing solutions for commercial applications. The LFSPXO009582 specifically addresses the need for a reliable 4MHz reference in compact electronic designs requiring minimal board space.

Replacement Considerations

Direct substitutes must match the 4MHz frequency, 3.3V supply, and 4-SMD 5x3.2mm footprint. Verify CMOS output compatibility and +/- 50 ppm stability tolerance. Cross-reference with other manufacturers' 4MHz SMD oscillators ensuring identical pinout and electrical characteristics.
