I assume that "clock up and down an analog output" means an up/down counter driving an A/D. Digital logic needs a min pulse width on clocks. The best I can think of right now would be to use each pulse to set a FF, run them through a synchronizer (pair of FFs), then bump the counter and clear the initial FF. That is, build a small circuit running on another clean clock that looks for the input pulses. -- These are my opinions, not necessarily my employer's.
