10. A phase locked loop, comprising: a controlled oscillator configured to output for outputting an oscillator signal at an output, and comprising an oscillator input; a loop filter, comprising a filter input and a filter output that is coupled to the oscillator input; and a phase/frequency detector comprising: a modulo counter configured to output a counter word having a predetermined word length based on the oscillator signal; a modulo integrator configured to output an integrator word having the predetermined word length as a function of an integration of a channel word; and a difference element comprising an output coupled to the filter input, wherein the difference element is configured to output a phase error word with the predetermined word length as a function of a difference between the counter word and the integrator word.
