DS1339U-33+ Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by VBAT. This ensures that the internal circuitry is properly initialized.
  • To ensure reliable oscillator startup, make sure the crystal is properly connected, and the oscillator capacitors are correctly sized. Also, ensure that the power supply is stable and within the recommended operating range.
  • The maximum frequency deviation of the DS1339U-33+ oscillator is ±20 ppm over the entire operating temperature range.
  • No, the DS1339U-33+ is not designed to operate with a battery voltage below 1.5V. The minimum recommended battery voltage is 1.5V.
  • To reset the DS1339U-33+, apply a low pulse to the RST pin. The duration of the pulse should be at least 1ms.
