Abstract:
In one embodiment, a phase lock loop circuit includes a control circuit, wherein the control circuit is configured to input an estimation having a second frequency and a second phase. The second frequency is selected from a range of frequencies including a first frequency from an acquired signal. A numerically controlled oscillator is coupled to the control circuit, wherein the control circuit is configured to control an output response of the numerically controlled oscillator. The numerically controlled oscillator is configured to receive the estimation from the control circuit and generate an output signal in response to the estimation. A phase detector is coupled to the control circuit and the numerically controlled oscillator, wherein the phase detector is configured to compare the first signal and the output signal and produce a comparison output, the comparison output indicative of a phase difference between the first signal and the estimation.
