@@ -31,13 +31,13 @@ The RTC timer has the following clock sources:
.. list::
- ``Internal 90-150 kHz (depending on chip) RC oscillator`` (default): Features the lowest Deep-sleep current consumption and no dependence on any external components. However, the frequency stability of this clock source is affected by temperature fluctuations, so time may drift in both Deep-sleep and Light-sleep modes.
- ``Internal 90–150 kHz (depending on chip) RC oscillator`` (default): Features the lowest Deep-sleep current consumption and no dependence on any external components. However, the frequency stability of this clock source is affected by temperature fluctuations, so time may drift in both Deep-sleep and Light-sleep modes.
:not esp32c2: - ``External 32 kHz crystal``: Requires a 32 kHz crystal to be connected to the external crystal pins. This source provides a better frequency stability at the expense of a slightly higher (by 1 μA) Deep-sleep current consumption. Refer to the `datasheet <{IDF_TARGET_DATASHEET_EN_URL}>`__ for information on which pins to connect to.
- ``External 32 kHz oscillator``: Allows using 32 kHz clock generated by an external circuit. The external clock signal must be connected to the external oscillator pin. The amplitude should be less than 1.2 V for sine wave signal and less than 1 V for square wave signal. Common mode voltage should be in the range of 0.1 < Vcm < 0.5xVamp, where Vamp stands for signal amplitude. Refer to the `datasheet <{IDF_TARGET_DATASHEET_EN_URL}>`__ for information on which pin to connect to.
:esp32 or esp32s2 or esp32s3 or esp32c2 or esp32c3: - ``Internal 8.5-17.5 MHz oscillator (depending on chip), divided by 256``: Provides better frequency stability than the ``Internal 90-150 kHz RC oscillator`` at the expense of a higher (by 5 μA) Deep-sleep current consumption. It also does not require external components.
:esp32 or esp32s2 or esp32s3 or esp32c2 or esp32c3: - ``Internal 8.5–17.5 MHz oscillator (depending on chip), divided by 256``: Provides better frequency stability than the ``Internal 90–150 kHz RC oscillator`` at the expense of a higher (by 5 μA) Deep-sleep current consumption. It also does not require external components.
The choice depends on your requirements for system time accuracy and power consumption in sleep modes. To modify the RTC clock source, set :ref:`CONFIG_RTC_CLK_SRC` in project configuration.
