The CC33xx device uses two clocks for operation:
The fast clock must be generated externally. The slow clock can be generated internally by the device or externally by an oscillator.
It is important to note that a deviation in clock frequency is reflected as a deviation in radio frequency. For more information on doing frequency tuning with careful selection of external loading capacitors (CL) depending on the layout, see Simplelink Frequency Tuning.
