Abstract: In described examples, an electronic circuit for determining a phase difference between a first clock signal and a second clock signal includes a timer circuit, circuitry for generating a selectively delayed transition of the second clock signal, and phase determination circuitry. The timer circuit produces an elapsed time between a transition of the first clock signal and the selectively delayed transition of the second clock signal. The circuitry for generating the selectively delayed transition of the second clock signal generates the selectively delayed transition in response to a random selection of a respective output from a plurality of second clock signal delay stages. The phase determination circuitry provides the phase difference in response to the elapsed time and the random selection of a respective output from a plurality of second clock signal delay stages.

Abstract: Aspects of the disclosure provide for an apparatus. In an example, the apparatus includes a clock switching circuit coupled to oscillators and one or more circuit units. The clock switching circuit is configured to receive, from the oscillators, a set of frequency signals, provide an uplink primary clock signal and an enable signal to the one or more circuit units, the enable signal determined synchronously with the uplink primary clock signal, receive, from the one or more circuit units or a clock management circuit, a clock frequency request, provide the uplink primary clock signal based on a first signal of the set of frequency signals, and according to the clock frequency request, determining whether to continue to provide the uplink primary clock signal based on the first signal or on a second signal of the set of frequency signals.

Abstract: A circuit for a phase-locked loop is described herein. The circuit includes a phase frequency detector configured to determine a phase error, a loop filter coupled to the phase frequency detector and configured to provide a clock control signal based on the phase error, and a controller coupled to the phase frequency detector and to the loop filter. The controller is configured to receive the phase error, detect a behavior of the phase error, and, responsive to the behavior of the phase error, perform a response that includes causing the phase frequency detector to adjust the phase error and causing the loop filter to adjust the clock control signal. Thus, the circuit may reduce settling time, overshoot, and/or undershoot in an output clock generated based on the clock control signal.

Abstract: Aspects of the disclosure provide for an apparatus comprising a time-to-digital converter (TDC) and a processor coupled to the TDC. In some examples, the TDC may be configured to receive a signal and generate a measurement result indicating a time between start and stop events of the signal. The processor may be configured to receive the measurement result, compare the measurement result to a target value, and determine a non-linearity model configured to correct a variance of the measurement result from the target value.
