Abstract

Clock recovery pulse signals for use in recovering transmitted data are generated by employing a digitally variable phase oscillator. The variable phase oscillator includes an oscillator having a substantially fixed frequency output signal, a phase encoder and a comparator. Coded phase values of the oscillator output signal are periodically generated by the phase encoder. These coded phase values are compared to a prescribed phase value to generate periodically clock recovery pulse signals. The prescribed phase value is obtained in one embodiment by storing the coded phase value being generated upon the occurrence of an incoming data transition and adding a predetermined phase value to it to center the clock recovery pulse signals substantially in the center of the incoming data eye pattern.
