LFSPXO056273

Overview

The LFSPXO056273 is a standard clock oscillator from the IQXO-794 series manufactured by IQD Frequency Products. It operates at a nominal frequency of 48 MHz with a frequency stability of ±50 ppm. The device supports an HCMOS output format and functions within a supply voltage range of 1.71 V to 1.89 V. It utilizes a surface-mount package measuring 2.5 mm x 2.0 mm x 1.0 mm. The component is rated for operation between -40°C and +85°C, featuring a load capacitance of 15 pF.

Feature Summary

• Provides precise timing signals via HCMOS output interface
• Operates on low voltage supply ranging from 1.71 V to 1.89 V
• Maintains frequency stability of ±50 ppm across operating conditions

Applications

• General purpose digital circuit clocking
• Embedded system timing references
• Consumer electronics internal clocks

Procurement Notes

Verify the specific suffix variant when ordering, as manufacturers may update part numbers without changing electrical characteristics. Confirm that the required supply voltage aligns with the 1.71 V to 1.89 V specification. Ensure the PCB footprint matches the 2.5 mm x 2.0 mm dimensions. Check RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a compact 48 MHz clock source is required for low-voltage logic circuits. The HCMOS output is suitable for direct interfacing with standard digital inputs. Consider the ±50 ppm stability requirement against system tolerance needs. The small SMD package aids in space-constrained designs where larger oscillators cannot fit.
