Crystal Oscillators for Smart Utility Meters

Smart utility meters require ultra-low power and high-precision crystal oscillators to support long-term accurate RTC timekeeping and reliable wireless data reporting, meeting the demand for up to 10 years of maintenance-free operation.

Key Clocking Requirements for Smart Utility Meters

  • High-Precision Timekeeping
    High-Precision Timekeeping

    Achieves a 32.768 kHz RTC accuracy of ≤±10 ppm (with premium options reaching ≤±5 ppm).

  • Ultra-Low Power Consumption
    Ultra-Low Power Consumption

    Supports a battery lifespan of 6 to 10 years through ultra-low operating and standby currents.

    Ensures fast start-up performance for rapid system response.

  • Industrial-Grade Wide-Temperature Reliability
    Industrial-Grade Wide-Temperature Reliability
