8.13 Clock Systems

The CC1314R10 device has several internal system clocks.

The 48MHz SCLK_HF is used as the main system (MCU and peripherals) clock. This can be driven by the internal 48MHz RC Oscillator (RCOSC_HF) or an external 48MHz crystal (XOSC_HF). Radio operation requires an external 48MHz crystal.

SCLK_MF is an internal 2MHz clock that is used by the Sensor Controller in low-power mode and also for internal power management circuitry. The SCLK_MF clock is always driven by the internal 2MHz RC oscillator (RCOSC_MF).

SCLK_LF is the 32.768kHz internal low-frequency system clock. It can be used by the Sensor Controller for ultra-low-power operation and is also used for the RTC and to synchronize the radio timer before or after Standby power mode. SCLK_LF can be driven by the internal 32.8kHz RC Oscillator (RCOSC_LF), a 32.768kHz watch-type crystal, or a clock input on any digital IO.

When using a crystal or the internal RC oscillator, the device can output the 32kHz SCLK_LF signal to other devices, thereby reducing the overall system cost.
