All CC131x and CC135x devices include internal variable load capacitors (in the IC) for adjusting the load capacitance of the external HF crystal without requiring external load capacitors.
For most use cases, TI recommends using an internal capacitor array, however, there are specific use cases where using external load capacitors is recommended. For more information on when TI recommends using external load capacitors, refer to the application note, CC13xx/CC26xx Hardware Configuration and PCB Design Considerations.
