Title: VIBRATION OPTIMIZING INTELLIGENT PHASE LOCKED LOOP
Abstract:
The present disclosure is directed towards systems and method for actively tuning a phase locked loop based on vibration excitation levels experienced by the phase locked loop. A bandwidth of the phase locked loop can be actively increased or decreased based upon a detected vibration level. In an embodiment, the phase locked loop includes a controllable oscillator, an output module, a filter module and a detector. The filter module can be configured to receive a bandwidth control signal to modify a bandwidth of the phase locked loop based on a vibration signal. In an embodiment, the vibration signal corresponds to a vibration level experienced by the phased locked loop. The detector can be configured to receive a PLL output signal from the output module and to receive a PLL input signal.
