(1) The input and output PLLs are calibrated at the ambient start up temperature (T_S) when the device is powered on or when reset using the PDB pin. The PLLs will stay locked up to the specified ending temperature. A more detailed description can be found in “Handling System Temperature Ramps on the DS90Ux949, DS90Ux929 and DS90Ux947”.
