Abstract: A reconfigurable digital phase-locked loop integrated circuit is disclosed which is coupleable to a reference frequency generator to generate an input signal having a reference frequency. A representative embodiment of the reconfigurable digital phase-locked loop integrated circuit may include a first digital phase-locked loop circuit configured to generate a first signal having a first frequency which is an integer multiple of the reference frequency; and a second digital phase-locked loop circuit coupled to the first digital phase-locked loop, the second digital phase-locked loop configured to generate a second, output signal having a second output frequency in response to a plurality of configuration parameters, the second frequency having a configurable fractional offset from the integer multiple of the reference frequency, and to match a phase of the second output signal with a first signal phase.
