DS1375T Frequently Asked Questions (FAQs)

• What is the recommended crystal oscillator frequency for the DS1375T?
  The recommended crystal oscillator frequency for the DS1375T is 32.768 kHz, which is a standard frequency for real-time clocks.
• How does the DS1375T handle battery switchover during power failure?
  The DS1375T has a built-in battery switchover circuit that automatically switches to the backup battery during power failure, ensuring continuous operation of the real-time clock.
• What is the accuracy of the DS1375T's internal oscillator?
  The accuracy of the DS1375T's internal oscillator is ±20 ppm over the operating temperature range of -40°C to +85°C, which is sufficient for most real-time clock applications.
• Can the DS1375T be used in a system with multiple power domains?
  Yes, the DS1375T can be used in a system with multiple power domains. It has a separate power pin for the battery-backed section, allowing it to operate independently of the main system power.
• How does the DS1375T handle clock calibration?
  The DS1375T has a built-in clock calibration circuit that allows for trimming of the internal oscillator frequency to improve accuracy. This can be done through the I2C interface.
