A detector to detect the magnitude of the jitter that may occur in a first clock signal and a second clock signal and to generate an alarm signal if the magnitude of the jitter exceeds the threshold value. The detector comprises a one-hot register storing a one-hot value comprising a first logic bit (=1) centered around one or more second logic bits (=0). The detector comprises a threshold register storing a threshold value comprising one or more second logic bits centered around one or more first logic bits. An event of a first clock rotates the contents of the one-hot value and an event of a second clock rotates the contents of the threshold value. A match between the pre-specified bit of the one-hot value and the threshold value indicates the occurrence of the jitter having a magnitude greater than the threshold value.
