Hi,
How fast can the slow DAC generate signals?
I need to generate 3 voltages sync'd to the same clock. Two are both ~40MHz. The third is sinewave up to 1kHz superimposed on a ~0.5 to 2Hz square wave. Hence, I'll want to generate the waveform at about 10Ksamples/second.
Right now, I am heading down the road of using two RPs connected via the SATA ports. I had hoped slaving the clock of one RP to the other would be straightforward. There is a blog that begins to describe this but it is incomplete. Koheron have a solution but I'm struggling to get it to work. Anton Potočnik's blogs have been a revelation and gave me a much better understanding of creating bitstreams etc.
Now I have an idea that if I build a custom bitstream then I could generate the third signal using the 125MHz and a clock counter to generate an appropriately slow clock. This would mean I could do everything on one RP.
Is this viable?
Many thanks,
John.

Re: Fastest slow DAC rate
You could use 2 fast analog outputs for the 40MHz signal and use 1 of the 4 Extension connector, for the slow output.
