spread spectrum oscillator clocking a DAC
spread spectrum oscillator clocking a DAC
(OP)
If a spread spectrum oscillator is used to clock a DAC or an ADC, I assume that there will be some distortion or noise introduced due to the intentional clock jitter. Is there a way of predicting the amount of additional distortion or noise if you know the spectrum bandwidth of the oscillator?
Thanks in advance,

But if the ADC/DAC is running at similar very high frequencies, them none of this would apply.

VE1BLL's point is interesting. I was originally thinking that any divided down versions of the clock would have a similar spread spectrum range, but in thinking about it, it seems like every division of the clock will change the frequency distribution to be closer to the center. Is that right?
