1. A clock recovery system comprising:

  • a source of a data signal;

    an injection-locked oscillator, coupled to the data signal source, having a free-running frequency and generating a clock signal; and

    a phase locked loop, coupled in parallel with the injection locked oscillator, and generating a control signal adjusting the free running frequency of the injection locked oscillator as a function of the clock signal and the data signal.
