I've a trouble to understand how exactly AD9761 works. Referring to it's data sheet I don't understand the figure 11 of page 13.
I don't know how the signals (select, write and clock) have to interact to actualize DAC's outputs, I can see at the input pins that bits are sent correctly but the output doesn't work correctly, that's why I think it's a problem with that signals that are not well synchronized.
Another doubt is that in the data sheet says that I&Q current outputs work identically. Does it mean that the bits sent to the in-phase and to the quad-phase register have to be the same, so the output has to be also the same? Or bits sent to I&Q have to be different?
Could anyone help me with it?
Thanks a lot.
