DAC NCO synchronization

Category: Hardware
Product Number: AD9081

I am trying to use the 4 DACs in the AD9081 at the same NCO frequency, and at the same NCO phase. This is part of a beamforming application.

I am using a ZCU102 and IIO to talk to the AD9081 eval board.

The NCO frequencies are all being set correctly. Is there a mechanism for causing all of the main datapath NCOs to synchronize phase? At present, the phases of the NCOs are different from each other, each time I run my program.

Thanks for your help.
