Hi,w
I ma using AD9778A Dac for 16QAM modulation. When i am programming DAC register it not giving output. Can you provide me the value of register i need to program so that i can get correct output.
Thanks.

We need to knoa a lot more information about what mode you are trying to use the AD9778 in to be able to help you. Are you using our eval board that include a quadrature modulator? Or is the AD9778 on your PCB. Please let us know what
data rate, what interpolation you need and if you need to use the NCO for complex modulation.
Itf you are using our eval board it is configured to bring the output to the AQM until you change some jumpers.

I should have said are you using coarse modulation instead of NCO.
