Are you basing that on the max frequency of the chip? This was what he said: "Sounds like we're way off the limits in terms of count capability of the 7i77. "transition distance" is set to 0.77 us Even at rapid of 2000 mm/min, we're only at 0.85333 Mhz into the 7i77 and 3.3 khz into the interpolator" -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Get 100% visibility into Java/.NET code with AppDynamics Lite!
