Abstract
A phase/frequency detector has a modulo counter for outputting a counter word with a predetermined word length depending on an oscillator signal. In addition, a modulo integrator for outputting an integrator word with the predetermined word length as a function of integration of a channel word is provided. The phase/frequency detector also has a difference element for outputting a phase error word with the predetermined word length as a function of a difference between the counter word and the integrator word.
