A clock signal generated by an external circuit can be connected to {IDF_TARGET_OSC_SLOW_PIN} to be the clock source for the ``RTC_SLOW_CLK``. This clock can also be calibrated to get its exact frequency.
.. only:: SOC_CLK_RC32K_SUPPORTED
- Internal 32 kHz RC Oscillator (RC32K)
The exact frequency of this clock can be computed in runtime through calibration.
Typically, the frequency of the signal generated from an RC oscillator circuit is less accurate and more sensitive to the environment compared to the signal generated from a crystal. {IDF_TARGET_NAME} provides several clock source options for the ``RTC_SLOW_CLK``, and it is possible to make the choice based on the requirements for system time accuracy and power consumption. For more details, please refer to :ref:`rtc-clock-source-choice`.
