PLL megacore probs.build my own??

...but you mentioned earlier that I need the phase accumulator from my NCO to build my pll

("if i understand right, you only need the phase accumulator from the nco to build your pll.").

As part of the pll, what would the input be for phase accumulator youre talking about? what I mean is that the NCO gets its input from the loop filter and adjusts its output simusoid accordingly & the that output goes back into the phase detector, who's output in turn goes into the loop filter ect..

So what Im asking is where in the pll does the phase accumulator you mention fit in?
