LFSPXO018379

Overview

The LFSPXO018379 is a standard clock oscillator from the CFPS-73 series by IQD Frequency Products. It operates at a nominal frequency of 4 MHz with a frequency stability of ±50 ppm. The device utilizes an HCMOS output format and requires a nominal supply voltage of 3.3 V. It is housed in a surface-mount package measuring 7 mm x 5 mm. This component is designed for applications requiring precise timing signals within standard industrial temperature ranges.

Feature Summary

• Provides stable 4 MHz clock signal generation
• Features HCMOS logic output compatibility
• Includes enable/disable control functionality
• Utilizes compact 7mm x 5mm SMD footprint

Applications

• Microcontroller system clocking
• General-purpose digital circuit timing
• Industrial control systems
• Communication interface synchronization

Procurement Notes

Verify the specific suffix or packaging variant required, as availability may vary between bulk and reel formats. Confirm that the 3.3V supply voltage aligns with the target board design. Ensure the ±50 ppm stability meets the system's timing tolerance requirements before finalizing the order.

Selection Notes

Select this model when a 4 MHz frequency is specifically required for synchronous digital logic. The 7x5mm package offers a balance between size and thermal performance compared to smaller footprints. Consider the enable pin feature if power management during idle states is necessary for the application.

Part Context

This part belongs to the CFPS-73 series of standard oscillators. It serves as a fundamental timing source for embedded systems. The series is characterized by its reliability and standard form factor, making it suitable for mass-produced electronic devices where consistent clock performance is critical.

Replacement Considerations

Direct substitutes must match the 4 MHz frequency, 3.3V supply, and 7x5mm package. Verify pinout compatibility and output drive strength. Check manufacturer-specific lead times and lifecycle status, as obsolescence notices may apply to older stock numbers.
