A sensor includes detection circuitry and control circuitry coupled to the detection circuitry. The detection circuitry generates a detection signal indicative of a detected physical quantity. The control circuitry, in operation receives the detection signal and a frequency-indication signal, and generates a trigger signal based on the frequency-indication signal and a set of local reference signals. The sensor generates a digital output signal and a locking signal based on the trigger signal and the detection signal. The generating the digital output signal includes outputting a sample of the digital output signal based on the trigger signal. The locking signal is temporally aligned with the digital output signal.
