No they are a completely different concept.
I did however manage to make something resembling a pitch tracker before with the A172 min/max or it might have been two of those... Like I said in an earlier thread I regret not notating that patch. :-(
Also forgot which piece of technical literature inspired me then... 
The A196 has some way more sophisticated circuits onboard.
Like mentioned in that earlier thread, the A196 is not a module on its own for a reason...

So, I’m buying an A-167 as it seems a pretty useful module to have. This is probably a very stupid question but is this the same ‘type’ (if there is such a thing) of comparator as the one in the A-196 If so, how would I go about assembling a PLL
