LFSPXO056240

Overview

The LFSPXO056240 is a standard clock oscillator from the IQXO-540 series by IQD Frequency Products. It operates at a nominal frequency of 19.44 MHz with a frequency stability of ±50 ppm. The device utilizes CMOS output format and supports an enable/disable function. It is designed for surface mount (SMD) installation within a compact 2mm x 1.6mm package. The component functions within a supply voltage range of 2.97 V to 3.63 V, typically centered around 3.3 V. It is rated for operation between -40°C and +85°C.

Feature Summary

• Compact 2mm x 1.6mm surface mount package design
• CMOS output signal format with enable/disable control
• ±50 ppm frequency stability over operating temperature range

Applications

• General purpose digital clock generation
• Microcontroller system timing references
• Embedded communication interface synchronization

Procurement Notes

Verify the specific frequency tolerance and package dimensions against the official IQD datasheet prior to integration. Confirm that the supply voltage requirements align with the target circuit design. Ensure the CMOS output load capabilities meet the downstream logic input specifications. Cross-reference the RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a small form factor oscillator is required for 19.44 MHz applications. The IQXO-540 series offers a balance of size and performance for space-constrained designs. Consider the ±50 ppm stability limit for timing-sensitive interfaces. The enable/disable feature allows for power management strategies in battery-operated systems.

Part Context

This part belongs to the IQXO-540 series of standard oscillators manufactured by IQD Frequency Products. The series provides various frequencies in a consistent 2mm x 1.6mm footprint. It is distinct from higher-stability TCXOs or wider-range VCXOs, focusing on cost-effective standard crystal oscillator performance for general electronics.

Replacement Considerations

Direct substitutes include other IQD models from the IQXO-540 series with identical pinout and frequency, such as LFSPXO056218 or LFSPXO056245. Verify electrical parameters match before swapping.
