LFSPXO009684

Overview

The LFSPXO009684 is a standard CMOS crystal oscillator manufactured by IQD Frequency Products, designed for precise timing applications. It operates at a fundamental frequency of 32.768 kHz with a frequency stability of ±50 ppm. The device functions on a 2.5V supply voltage and features an enable/disable control function. It utilizes a basic crystal resonator and delivers a CMOS output signal. The component is housed in a compact 4-SMD, no-lead package with dimensions of 2.60mm x 2.10mm and a maximum height of 0.95mm. It supports surface mount installation and operates within a temperature range of -40°C to +85°C, drawing a maximum supply current of 2.5mA.

Feature Summary

• Integrates a CMOS output stage for direct logic interface compatibility
• Includes hardware enable/disable functionality for power management control
• Utilizes a hermetically sealed ceramic package for environmental protection
• Provides stable 32.768 kHz timing reference suitable for real-time clocks

Applications

• Real-time clock circuits in embedded systems
• Low-power portable electronic devices requiring precise timekeeping
• Industrial control systems operating in extended temperature ranges
• Consumer electronics utilizing standard CMOS logic interfaces

Procurement Notes

Verify the specific suffix and packaging configuration when ordering, as availability may vary between tape-and-reel and cut-tape formats. Confirm that the 2.5V supply requirement aligns with the target system's voltage rails. Ensure the 4-SMD footprint matches the PCB layout constraints. Check for any recent part number revisions or lifecycle notices from IQD Frequency Products prior to finalizing procurement plans.

Selection Notes

Select this component when a low-frequency, high-stability timing source is required for CMOS-based digital circuits. The 32.768 kHz frequency is optimal for binary division to generate one-second intervals. Consider the ±50 ppm stability specification against the system's timing tolerance requirements. Evaluate the 2.5V operating voltage against available power supplies, noting that it differs from standard 3.3V or 5V logic levels without level shifting.

Part Context

This oscillator belongs to the broader category of surface-mount crystal oscillators provided by IQD Frequency Products. It serves as a specialized timing element distinct from general-purpose high-frequency clock generators. The 32.768 kHz frequency is a industry-standard value derived from binary division of higher frequencies, making it ubiquitous in timekeeping applications across various electronic sectors.

Replacement Considerations

Direct substitutes must match the 32.768 kHz frequency, CMOS output type, 4-SMD package dimensions, and 2.5V supply voltage. Verify that alternative components offer comparable ±50 ppm stability and support the same enable/disable pin configuration. Cross-reference mechanical footprints and thermal characteristics to ensure board compatibility.
