I have this question about clocking data into the AD9364. In the AD9364 Reference Manual UG-673 document, on p.87 and p.99 it says that " Note that FB_CLK must be a feedback version of DATA_CLK (exact same frequency and duty cycle) …". So, if you are building a transmitter only, and don't care about the receiver functionality, do you still have to have the DATA_CLK generated from the AD9364 to be able to clock transmit data into it using the FB_CLK? I.e. does this relationship hold, even if you need no receiver functionality?
