LFSPXO018043

Overview

The LFSPXO018043 is a standard clock oscillator from the CFPS-73 series by IQD Frequency Products. It operates at a nominal frequency of 48 MHz with a frequency stability of ±50 ppm. The device utilizes an HCMOS output format and requires a supply voltage range of 2.97 V to 3.63 V, typically centered at 3.3 V. It features a load capacitance of 50 pF and supports Enable/Disable functionality. The component is housed in a surface-mount package measuring 7 mm x 5 mm x 1.4 mm. It is designed for operation within a temperature range of 0°C to +70°C.

Feature Summary

• Provides stable 48 MHz clock signals with ±50 ppm accuracy
• Features HCMOS output format compatible with digital logic
• Includes Enable/Disable control for power management

Applications

• General-purpose digital circuit timing
• Microcontroller clock sources
• Embedded system synchronization

Procurement Notes

Verify the specific operating temperature grade required for your application, as the CFPS-73 series includes variants rated for both 0°C to +70°C and -40°C to +85°C. Confirm that the 50 pF load capacitance matches your circuit design requirements. Ensure the 3.3V supply voltage aligns with your system's power rails. Check for any specific ordering suffixes that might indicate different packaging or temperature ranges.

Selection Notes

Select this model when a precise 48 MHz reference is needed for digital interfaces. The HCMOS output is suitable for direct connection to CMOS-compatible inputs. Consider the physical dimensions (7x5mm) for PCB layout constraints. Verify that the ±50 ppm stability meets the jitter and timing tolerance requirements of the downstream components. Ensure the Enable/Disable pin is utilized if power saving is a priority.

Part Context

This part belongs to the CFPS-73 series of standard crystal oscillators (SPXOs). This series offers various frequencies and stability options in compact SMD packages. It is distinct from higher-stability TCXOs or low-jitter models, focusing on cost-effective standard timing solutions for general electronics applications.

Replacement Considerations

Direct substitutes may include other 48 MHz HCMOS oscillators with similar footprint and electrical characteristics. Cross-reference with other manufacturers' 48MHz SPXOs ensuring matching voltage, load capacitance, and temperature range. Verify pinout compatibility before replacement.
