Aspects of a method and system for a fast-switching Phase-Locked Loop using a Direct Digital Frequency synthesizer may include generating a second signal from a first signal by: frequency translating an inphase component of the first signal utilizing a filtered fast-switching oscillating signal generated using at least a direct digital frequency synthesizer (DDFS), and frequency translating a corresponding quadrature component of the first signal utilizing a phase-shifted version of the generated and filtered fast-switching oscillating signal. The inphase and quadrature components of the first signal may be multiplied with the filtered fast-switching oscillating signal and a phase-shifted version of the filtered fast-switching oscillating signal, respectively. The filtered fast-switching oscillating signal may be obtained by removing at least one frequency-sum term of the fast-switching oscillating signal, where the fast-switching signal oscillating signal may be generated from a signal generated by the DDFS that may be multiplied with an oscillating reference signal.
