LFSPXO056247

Overview

The LFSPXO056247 is a standard clock oscillator from the IQXO-540 series manufactured by IQD Frequency Products. It operates at a nominal frequency of 40 MHz with a frequency stability of 50 ppm. The device utilizes CMOS output format and requires a supply voltage ranging from 2.97 V to 3.63 V, typically centered at 3.3 V. It features an enable/disable function for power management. The component is housed in a compact 4-SMD, no lead package measuring 2.0 mm x 1.6 mm x 0.7 mm. It supports surface mount termination and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrated enable and disable functionality for active power control
• Compact 4-SMD no-lead surface mount package design
• CMOS output signal format suitable for digital logic interfaces

Applications

• General purpose clock generation for embedded systems
• Timing reference for microcontrollers and processors
• Data communication interface synchronization

Procurement Notes

Verify the specific ordering suffix to confirm the required packaging type, such as cut tape or reel, as these affect handling procedures. Ensure the selected variant matches the exact frequency tolerance and supply voltage requirements of the target circuit design. Cross-reference the manufacturer part number with official distributor catalogs to confirm current availability and RoHS compliance status before finalizing procurement.

Selection Notes

Select this oscillator when a 40 MHz timing source with 50 ppm stability is required in a minimal footprint. The 3.3 V supply compatibility makes it suitable for standard logic families. Consider the enable pin requirement if dynamic power saving is necessary. Compare against other IQXO-540 variants if different frequencies or package sizes are needed for the specific PCB layout constraints.

Part Context

This component belongs to the IQXO-540 series of standard crystal oscillators produced by IQD Frequency Products. The series offers various frequencies and package options designed for space-constrained applications. The LFSPXO056247 specifically addresses the need for a reliable 40 MHz clock signal in a small SMD form factor, fitting within the broader portfolio of surface-mount frequency control solutions.

Replacement Considerations

Direct substitutes within the same series include LFSPXO056249 (50 MHz) and LFSPXO056237 (12 MHz), provided the frequency difference is acceptable for the application. Other IQD Frequency Products oscillators with identical 2x1.6mm packages and CMOS outputs may serve as alternatives if electrical parameters align.
