A time-to-digital converter circuit includes a logic gate coupled to receive a first trigger signal indicative of a first clock signal and a second trigger signal indicative of a second clock signal. The logic gate is to generate a logic gate output signal responsive to the earlier of the first or second trigger signals to be a logic high. A synchronization circuit is included and is coupled to the logic gate and is configured to synchronize the logic gate output signal to a third clock to produce a synchronization output signal. A counter circuit counts pulses of the synchronization output signal.
