Abstract
In an example, a system includes a phase frequency detector (PFD) coupled to a charge pump, and a loop filter coupled to the charge pump. The system also includes a voltage controlled oscillator (VCO) coupled to the loop filter. The system includes a fast Fourier transform (FFT) engine coupled to an output of the VCO, the FFT engine configured to estimate a phase and a magnitude of reference spurs of an input reference signal. The system includes spur correction circuitry coupled to an input of the VCO, the spur correction circuitry configured to correct for the reference spurs of the input reference signal based at least in part on the phase and magnitude of the reference spurs.
