Specific Phase between two WaveDAC Sine Waves
I need to use a WaveDAC to create a sine wave (audio frequencies) output (know how to do that), and contemporaneously a 2nd one (2nd WaveDAC) which has a (digitally) known / programmable phase delay - from 0 to 360 deg w.r.t the first. Seems like the start of adress incrementing in the table lookup happens at WaveDAC8_Start time - (if the clock is going) which would not create a precise phase difference if used to delay the start of the 2nd. Also - any approach which started the 2nd WaveDAC's clock at a known delay w.r.t the first WaveDAC's clock could be subject to error over long time (hoping they stay in the known phase relationship - not "re-setting" that relationship every cycle. Any thoughts on a configuration which would re-assert the phase relationship every cycle?
