It is recommended that the 1.8V supplies (DVDD, RF1VDD and RF2VDD) be brought up and the RESETN pin
driven low before the analogue supply (AVDD) is brought up. The charge pump supplies (CP1VDD, CP2VDD)
can be brought up either before or after the other supplies. If this sequence is not followed then the analogue
circuits may power up in an indeterminate or active state, and this state may persist until the 1.8V supplies
are brought up and the RESETN pin is driven low. The CMX983 will not suffer physical damage or reliability
degradation if the recommended power up sequence is not followed.
