6.8 Clock Systems

The CC1350 device supports two external and two internal clock sources.

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

The 32.768-kHz crystal is optional. The low-speed crystal oscillator is designed for use with a 32.768-kHz watch-type crystal.

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

The internal low-speed RC oscillator (32-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.
