LFSPXO018379BULK

Overview

The LFSPXO018379BULK is a standard clock oscillator from the IQD Frequency Products CFPS-73 series. It operates at a nominal frequency of 4 MHz with a frequency stability of 50 PPM. The device features an HCMOS output format and requires a supply voltage ranging from 2.97 V to 3.3 V. It is housed in a surface-mount package measuring 7.0 mm x 5.0 mm x 1.4 mm. The component supports a load capacitance of 50 pF and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Provides stable HCMOS clock signals for digital circuit timing
• Compact surface-mount design suitable for space-constrained PCB layouts
• Operates on low voltage power supplies for energy efficiency

Applications

• General-purpose digital system clock generation
• Microcontroller and microprocessor timing references
• Communication interface synchronization circuits

Procurement Notes

Verify the specific suffix and packaging configuration when ordering, as bulk packaging may differ from tape-and-reel variants. Confirm that the 50 PPM stability meets your system requirements. Check current availability status as distribution channels may list varying stock levels or end-of-life notices. Ensure the 7x5mm footprint matches your board design constraints before finalizing procurement.

Selection Notes

Select this model when a 4 MHz reference signal is required with moderate stability. The 50 PPM tolerance suits applications less sensitive to drift than TCXOs. Verify the 2.97V minimum supply voltage compatibility with your logic levels. The 7x5mm package offers a balance between size and thermal performance compared to smaller footprints.

Part Context

This component belongs to the CFPS-73 series of standard oscillators manufactured by IQD Frequency Products. The series provides various frequencies and stability options in compact packages. The LFSPXO018379BULK specifically targets the 4 MHz market segment with standard CMOS outputs.

Replacement Considerations

Check for direct cross-reference part numbers from IQD or other manufacturers offering identical 4MHz/50PPM/HCMOS specifications in a 7x5mm package. Ensure pinout compatibility if substituting with different brands.
