Is the data written into the AD5781 will be read out from SDO in next SYNC PHASE?
Could you clarify what are the signals shown in the digital analyzer? I'm guessing it's SYNC, SCLK, SDIN, and SDO. Is this accurate? Also, would you be able to get a scope shot from an oscilloscope and not from a digital analyzer? Could you also share what is your clock frequency, what you are trying to do, and what is it the problem that you are having?
What is your target application with this? It would greatly help us understand if you could provide a schematic diagram of your circuit.
