yes, I have two daughterboards(Basic TX). I can now send two independent
signals from the two daugterboards, but the two signals have the same
phase.

How can I control the phase on power-up?

But if the two signals come out of the FPGA with different phase,
because each one of the signals will go to different AD9862. I would
think that the phase should be controlled from the FPGA and the AD9862
will have nothing to do with the phase, probably not :).
