LFSPXO050757

Overview

The LFSPXO050757 is a standard clock oscillator from the CFPS-39 series by IQD Frequency Products. It operates at a nominal frequency of 40 MHz with a frequency stability of 25 ppm. The device supports a supply voltage range of 2.97 V to 3.63 V and features an HCMOS output format. Designed for surface mount applications, it utilizes a compact SMD package measuring 3.2 mm x 2.5 mm. The component is rated for an operating temperature range from 0°C to +70°C.

Feature Summary

• Delivers precise timing signals with 25 ppm frequency stability
• Utilizes low-profile surface mount packaging for space-constrained designs
• Supports standard CMOS logic levels for direct interface compatibility

Applications

• General purpose digital circuit timing
• Embedded system clock generation
• Industrial control equipment synchronization

Procurement Notes

Verify the specific operating temperature grade required for your application, as the CFPS-39 series includes variants rated for commercial (0°C to +70°C) and extended industrial (-40°C to +85°C) ranges. Ensure the selected part number corresponds to the correct thermal specification. Confirm that the 3.2mm x 2.5mm footprint matches your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when a stable 40 MHz reference is needed in a small form factor. The 25 ppm stability suits most general digital applications. Consider the CFPS-39 series if lower power consumption or different voltage options are not critical. Verify that the HCMOS output swing meets the input requirements of the downstream logic devices in the design.

Part Context

This oscillator belongs to the CFPS-39 series, which focuses on miniaturized standard clock solutions. IQD Frequency Products integrates these components into broader timing portfolios used across automotive, computing, and industrial sectors. The series emphasizes reliability and compactness, aligning with modern electronics trends toward smaller, more efficient circuit boards.

Replacement Considerations

Check for direct cross-references within the CFPS-39 family for alternative frequencies or stability grades. Other manufacturers may offer similar 3.2x2.5mm oscillators, but pinout and electrical characteristics must be verified against the official datasheet to ensure functional compatibility.
