Abstract: A phase lock loop circuit. The phase lock loop circuit includes first and second pass gates. The pass gates include signal inputs that receive first and second reference signals, respectively. The pass gates also have enable inputs. The phase lock loop also includes a loop filter that is coupled to the outputs of the first and second pass gates. A loop oscillator is coupled to the output of the loop filter. A strobe circuit is coupled to the output of the loop oscillator. The strobe circuit provides an input signal to the enable inputs of the first and second pass gates so as to sample the first and second reference signals. The loop filter uses the samples of the first and second reference signals to create a control signal that forces the loop oscillator to output a signal with a phase that is between the phases of the first and second reference signals.
