LFSPXO018041BULK

Overview

The LFSPXO018041BULK is a standard clock oscillator manufactured by IQD Frequency Products. It operates at a nominal frequency of 4.0 MHz with a frequency stability of 50 ppm. The device utilizes an HCMOS output format and is housed in a surface-mount package measuring 7.0 mm x 5.0 mm. It features a hermetically sealed ceramic package with a seam-sealed metal lid, belonging to the CFPS-73 series.

Feature Summary

• Hermetically sealed construction using a ceramic package with a seam-sealed metal lid for environmental protection
• HCMOS output format suitable for digital logic interfacing
• Surface-mount design within a compact 7.0 mm x 5.0 mm footprint

Applications

• General purpose timing reference for digital circuits
• Clock signal generation in embedded systems
• Industrial control equipment requiring stable frequency sources

Procurement Notes

Verify the specific operating voltage range and temperature specifications against the official datasheet before integration, as bulk packaging variants may have distinct electrical constraints compared to tape-and-reel versions. Confirm RoHS compliance status and lead times with authorized distributors, ensuring the component meets current regulatory requirements for the target market.

Selection Notes

Select this component when a hermetically sealed crystal oscillator is required for robust performance in demanding environments. The 4.0 MHz frequency and 50 ppm stability suit applications needing precise timing without the complexity of TCXOs. Ensure the PCB layout accommodates the 7x5mm SMD footprint and that the HCMOS output levels match the receiving logic family.

Part Context

This part belongs to the CFPS-73 series of standard oscillators from IQD Frequency Products. These devices are designed for applications requiring reliable, low-phase-noise clock signals. The series offers various frequencies and packages, with the LFSPXO018041BULK specifically providing a 4.0 MHz output in a bulk-packaged SMD form factor.

Replacement Considerations

Direct substitutes include other IQD Frequency Products oscillators with identical 4.0 MHz frequency, 50 ppm stability, and 7x5mm SMD package dimensions. Verify pinout compatibility and supply voltage requirements when considering alternative manufacturers' equivalents.
