Abstract:
A phase lock loop (PLL), such as an all digital phase lock loop (ADPLL) to provide an example, of the present disclosure operates in a frequency tracking mode to adjust a frequency of the output signal to be proportional to a frequency of a reference input signal, or, in a phase tracking mode to adjust a phase of the output signal to match any variations in the reference input signal. The ADPLL includes a phase and/or frequency detector that provides an error signal representing a difference, in frequency and/or phase, between the output signal and the reference input signal. The ADPLL monitors a trend of the error signal, such as a positive trend, a negative trend, or a flat trend to provide some examples, and switches among the frequency tracking mode and the phase tracking mode upon detecting a change in the trend of the error signal.

Claim (Index 1):
A phase lock loop (PLL) controller, comprising:\n a trend detector configured to:\n sample an error signal, the error signal representing a difference between a reference input signal of the PLL and an output signal of the PLL, and \n determine a trend of the sampled error signal; and \n a trend change detector configured to initiate a change in a mode of operation of the PLL upon detecting a. change in the trend of the sampled error signal from a previous trend of the sampled error signal.
