LFSPXO009440

Overview

The LFSPXO009440 is a standard clock oscillator from the IQD CFPS-73 series, operating at a nominal frequency of 125 MHz. It utilizes an HCMOS output format and requires a 3.3V supply voltage. The device features enable/disable functionality and offers a frequency stability of ±50 ppm. Designed for surface mount installation, it is housed in a compact 4-SMD, no-lead package measuring 7.20 mm x 5.20 mm with a maximum height of 1.40 mm. The component supports an industrial operating temperature range of 0°C to +70°C and has a maximum supply current of 40 mA.

Feature Summary

• Provides stable HCMOS clock signals with integrated enable and disable control capabilities
• Utilizes a crystal-based resonator for reliable frequency generation within a compact SMD footprint
• Operates on a single 3.3V power supply with low current consumption suitable for portable applications

Applications

• High-speed digital logic timing references
• Data communication interface clocks

Procurement Notes

Verify the specific suffix against official IQD documentation to confirm packaging type, as bulk and reel variants exist for this series. Ensure the selected part matches the required frequency stability and temperature range specifications for the target application environment. Cross-reference the manufacturer part number with authorized distributors to confirm current availability and lead times prior to ordering.

Selection Notes

Select this component when a 125 MHz HCMOS clock signal is required in a small surface-mount package. Consider the ±50 ppm stability requirement and the 0°C to +70°C operating range to ensure compatibility with the system's thermal and timing constraints. Verify that the 3.3V supply voltage aligns with the design's power architecture and that the enable pin functionality meets control requirements.

Part Context

This oscillator belongs to the CFPS-73 series by IQD Frequency Products, designed for general-purpose timing applications. The series offers various frequencies and stability options in standardized SMD packages. The LFSPXO009440 specifically targets high-frequency digital systems requiring precise timing with moderate stability levels in a cost-effective form factor.

Replacement Considerations

Check for direct substitutes within the CFPS-73 series offering identical 125 MHz frequency and ±50 ppm stability. Verify pinout compatibility and electrical parameters such as supply voltage and output drive strength before substituting.
