Abstract
An interpolator testing system comprises an interpolator that generates M clock signals having phase shifts in increments of 360/M degrees relative to a reference clock signal and that outputs one of the M clock signals as a recovered clock signal. A recovered clock counter counts an attribute of the recovered clock signal, wherein the interpolator sequentially selects the M clock signals N times, wherein M and N are integers greater than one.
