(1) Probing or otherwise stopping the crystal 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 CC2640Q1EM-7ID reference design with Tc = 25°C, VDDS = 3.0 V
(4) Includes initial tolerance of the crystal, drift over temperature, ageing and frequency pulling due to incorrect load capacitance, as per Bluetooth specification.
(5) Kick-started based on a temperature and aging compensated RCOSC_HF using precharge injection.
