Abstract
A circuit for detecting delay of more than a set period of time from a last signal transition for any of a plurality of data signals, comprising a differential comparator, and integrator pairs for each signal, one integrator of the pair being triggered by transition of the signal from low to high and the other triggered by transition of the inverse of the signal from low to high, each integrator having a voltage measured by the differential comparator against a reference voltage, each integrator being reset by the trigger for the other integrator.
