I would like to use the AD9361 for a MIMO radar application. I have seen on this discussion board many suggestions for how to synchronize clocks for receive, but have not seen the transmit issue addressed. Is there already a built-in solution to synchronize the timing of the transmit function across multiple chips? How is the timing for transmit determined? Is it a rising edge of one of the clocks? Can you program a delay time after the rising edge for the transmit? If you have this level of control, I can see how if you synchronize the clocks you would be able to calibrate the transmit to account for any path length differences.
