    Hello.
    
 
    Does the AD9985A need special power-up/down sequence for VD, VDD and PVD?
    
 
    Thanks!

    First of all the AD9985A is not recommended for new designs.  
    
 
    Since all three power rails are the same voltage I'd just recommend that they stay close together as the come up or go down.
