Hello ADI people,


   Can VDD_INTERFACE of AD9361 can be temporary off when AD9361 is in SLEEP/WAIT state? For power saving, what I like to do is as below sequence. 


a) Switch AD9361 to ALERT mode first then go to SLEEP or WAIT mode.

b) Power down external PMIC which is in charge of VDD_INTERFACE of AD9361.


To wake up whole system that includes AD9361.

c) Power up VDD_INTERFACE of AD9361 first.

d) Set AD9361 to ALERT mode from SLEEP or WAIT mode.

e) Manipulate AD9361 normally per system request. 


Can someone confirm that temporary off of VDD_INTERFACE is OK for following manipulation? If not, please explain more in details of the reason. Thanks in advance.
