Abstract
An Integrated Circuit (IC) includes a digital phase-locked loop (DPLL) circuit and DPLL Diagnostics circuitry (DPLL-DC). The DPLL circuit includes an oscillator, a digital phase detector and a digital feedback bus (DPLL-DFB). The oscillator is configured to generate an output signal. The digital phase detector is configured to generate a digital feedback signal indicative of a phase difference between the output signal and a reference input signal. The DPLL-DFB is configured to feed-back the digital feedback signal for controlling the oscillator. The DPLL-DC is coupled to the DPLL-DFB and is configured to monitor events depending at least on the digital feedback signal transferred on the DPLL-DFB.
