LFSPXO073905

Overview

The LFSPXO073905 is a standard crystal clock oscillator from IQD Frequency Products, designed for surface-mount applications. It operates at a nominal frequency of 32.768 kHz with a frequency stability of ±30 ppm across an industrial temperature range of -40°C to +85°C. The device supports a supply voltage of 3.3 V and features CMOS output logic. It includes enable/disable functionality and is housed in a compact 4-SMD, no-lead package.

Feature Summary

• Integrated enable and disable control function for power management
• CMOS output logic compatible with standard digital interfaces
• Compact surface-mount package design for space-constrained layouts

Applications

• Real-time clock circuits
• Microcontroller system clocks
• Low-frequency timing references

Procurement Notes

Verify the specific suffix and packaging variant when ordering, as availability may vary by distributor. Confirm that the 3.3V supply requirement aligns with your system design. Ensure the ±30 ppm stability meets your timing accuracy needs. Check for any lead time constraints associated with this component before finalizing procurement plans.

Selection Notes

Select this oscillator when a precise 32.768 kHz reference is required for low-power or cost-sensitive designs. The CMOS output simplifies interface requirements compared to other logic families. Consider the ±30 ppm stability limit against your system's jitter tolerance. The wide operating temperature range suits diverse environmental conditions.

Part Context

This component belongs to IQD’s standard SPXO series, which provides reliable frequency generation for general-purpose electronics. It complements higher-stability TCXOs and VCXOs by offering a cost-effective solution for non-critical timing applications where moderate stability suffices.

Replacement Considerations

Cross-reference with other 32.768 kHz CMOS oscillators from manufacturers like Epson or NDK. Verify pinout compatibility and electrical parameters such as supply voltage and load capacitance before substitution.
