Clock Systems

The CC2640R2F supports two external and two internal clock sources.

A 24-MHz crystal is required as the frequency reference for the radio. This signal is doubled internally to create a 48-MHz clock.

The 32-kHz crystal is optional. Bluetooth low energy requires a slow-speed clock with better than
±500 ppm accuracy if the device is to enter any sleep mode while maintaining a connection. The internal
32-kHz RC oscillator can in some use cases be compensated to meet the requirements.
The low-speed crystal oscillator is designed for use with a 32-kHz watch-type crystal.

The internal high-speed oscillator (48-MHz) can be used as a clock source for the CPU subsystem.

The internal low-speed oscillator (32.768-kHz) can be used as a reference if the low-power crystal oscillator is not used.

The 32-kHz clock source can be used as external clocking reference through GPIO.
