LFXTAL078719

Overview

The LFXTAL078719 is a surface-mount quartz crystal from the CFPX-218 series by IQD Frequency Products. It operates at a fundamental frequency of 25 MHz with a frequency stability of ±10 ppm. The component features a load capacitance of 10 pF and an equivalent series resistance of 100 Ohms. It utilizes an HCMOS output format and is housed in a compact 7.5 mm x 5 mm SMD/SMT package, though specific dimensions are listed as 2.5mm x 2mm in some sources. The operating temperature range extends from -10°C to +70°C.

Feature Summary

• Provides stable 25 MHz timing reference for digital circuits
• Compact surface-mount design suitable for space-constrained PCBs
• Operates within standard industrial temperature ranges

Applications

• Microcontroller clock generation
• Communication interface synchronization
• Digital signal processing systems

Procurement Notes

Verify the exact package dimensions against the official datasheet, as conflicting measurements exist between 2.5x2mm and 7.5x5mm descriptions. Confirm the operating temperature range specification (-10C to +70C) matches the specific reel or tape variant being ordered. Ensure load capacitance requirements align with the target circuit design before procurement.

Selection Notes

Select this component when a 25 MHz fundamental frequency with ±10 ppm stability is required. The 10 pF load capacitance must match the oscillator circuit's external capacitor values. Consider the SMD form factor for automated assembly processes. Verify that the 100 Ohm ESR is compatible with the driving circuit's power limitations.

Part Context

This part belongs to the CFPX-218 series of surface-mount quartz crystals. It serves as a passive frequency control element, distinct from active oscillators. The component requires an external oscillator circuit to generate a square wave signal, unlike the LFSPXO014933 which is an active clock oscillator.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation.
