(1) Probing or otherwise stopping the XTAL while the DC-DC converter is enabled may cause permanent damage to the device.
(2) The crystal manufacturer's specification must satisfy this requirement
(3) Measured on the TI CC2650EM-5XD reference design with T_c = 25°C, V_DDS = 3.0 V
(4) Includes initial tolerance of the crystal, drift over temperature, ageing and frequency pulling due to incorrect load capacitance. As per
IEEE 802.15.4 specification.
(5) Kick-started based on a temperature and aging compensated RCOSC_HF using precharge injection.
