[sdiy] DCO Question

[Tim Ressel]

Hi,

I am making a digital oscillator (DCO) and was wondering if there is a 
way to reduce the jitter one gets at higher frequencies. I understand it 
comes from round off error (for lack of a better term): as the 
accumulator reaches the top of the range the remaining amount is less 
than the value being added, and that fraction changes every cycle. This 
causes jitter, or is it aliasing? Anyway, is there a clever way to deal 
with it?

Thanks!
