PRODUCTION DATA.
When the PDN pin = 0, the device enters a complete power down mode with a current consumption of no more than 1 mA from the entire device. Exiting power down resets the entire device and defaults all registers. It is recommended to connect a capacitor between the PDN pin and GND to implement a RC time delay and ensure the digital and PLL related power supplies are stable before the device calibration sequences is initiated. Refer to Power Rail Sequencing, Power Supply Ramp Rate, and Mixing Supply Domains for more details.
