Overview
The LFSPXO071977 is a surface-mount crystal oscillator from the IQXO-986 series by IQD Frequency Products. It operates at a nominal frequency of 32.768 kHz with a frequency stability of +/- 50 ppm. The device utilizes CMOS output levels and requires a nominal supply voltage of 1.8 V. It is housed in a compact SMD package measuring 1.6 mm x 1.2 mm. The component supports an enable/disable function and is designed for operation within a minimum temperature range of -40°C.
Feature Summary
- Compact 1.6mm x 1.2mm surface-mount footprint suitable for space-constrained designs
- CMOS output interface compatible with standard digital logic circuits
- Integrated enable/disable control functionality for power management
Applications
- Real-time clock circuits in portable electronic devices
- Low-power embedded systems requiring precise timekeeping
- Consumer electronics utilizing 32.768 kHz reference frequencies
Procurement Notes
Verify that the required operating temperature range meets the application's minimum threshold of -40°C. Confirm that the system power rail provides a stable 1.8V nominal supply to ensure correct CMOS output levels. Ensure PCB layout accommodates the specific 1.6mm x 1.2mm SMD package dimensions for proper soldering and mechanical stability.
Selection Notes
Select this component when a low-profile, low-voltage oscillator is required for timing applications. The 32.768 kHz frequency is standard for clock division, while the 50 ppm stability offers adequate precision for general timekeeping. Consider the 1.8V supply constraint and CMOS output compatibility against other available voltage options and output types in the IQXO-986 series.
Part Context
This part belongs to the IQXO-986 series of ultra-small crystal oscillators from IQD Frequency Products. The series focuses on miniaturization for modern handheld and wearable devices. The LFSPXO071977 specifically addresses the need for reliable 32.768 kHz timing in a minimal footprint, distinguishing it from larger through-hole or standard SMD oscillator packages.
Replacement Considerations
Direct substitutes must match the 32.768 kHz frequency, 1.8V supply, and 1.6x1.2mm package. Verify pinout compatibility and CMOS output type. Cross-reference with other manufacturers offering similar small-form-factor RTC oscillators if IQD stock is unavailable.
