AD9914/15 SYNC_CLK outputs during DAC calibration with synchronisation

I am planning to use multiple AD9914 with synchronisation, I am also phanning to use the SYNC_CLK outputs to syncrhonise other circuitries. I wonder what happen to these SYNC_CLK outputs during a calibration with synchronisation? because of the synchronisation activity one assumes that the SYNC_CLK outputs will be at least temporary disturbed to effect the synchronisation but I also wonder whether they will also be turned off during the whole of the calibration period just as they are during RESET. It is important for us to know this in order to arrange a replacement for the SYNC_CLK signals during calibration if necessary.
