LFSPXO056266

Overview

The LFSPXO056266 is a standard clock oscillator from the IQXO-794 series manufactured by IQD Frequency Products. It operates at a nominal frequency of 20 MHz with a frequency stability of 50 ppm. The device utilizes HCMOS output format and supports a supply voltage range from 1.8 V to 3.6 V, typically operating at 2.5 V or 3.3 V. It features an SMD package measuring 2.5 mm x 2 mm.

Feature Summary

• Provides stable 20 MHz timing signals via HCMOS output interface
• Operates within a wide low-voltage supply range for flexible integration
• Compact surface-mount footprint suitable for space-constrained designs

Applications

• General purpose digital circuit clock generation
• Microcontroller and microprocessor system timing
• Communication equipment signal synchronization

Procurement Notes

Verify the specific supply voltage variant required for your application, as the series supports multiple voltage options. Confirm the packaging type matches your assembly process needs. Ensure compatibility with the target load capacitance and drive strength requirements of the receiving circuitry before finalizing procurement.

Selection Notes

Select this component when a compact, low-voltage HCMOS oscillator is needed for 20 MHz applications. Consider the 50 ppm stability specification against system jitter requirements. Evaluate the 2.5 mm x 2 mm package dimensions against available PCB real estate constraints compared to larger standard packages.

Part Context

This part belongs to the IQXO-794 series of standard oscillators from IQD Frequency Products. The series offers various frequencies and voltages in small SMD packages, targeting cost-sensitive consumer and industrial electronics requiring reliable timing sources without the complexity of TCXOs or VCXOs.

Replacement Considerations

Check for direct cross-reference parts from IQD such as other LFSPXO variants with identical pinouts and electrical characteristics. Verify that any substitute maintains the same 20 MHz frequency, HCMOS output logic levels, and 2.5x2mm package dimensions to ensure mechanical fit.
