Abstract

See full text

A semiconductor system may include a first semiconductor device configured to output a clock, receive and output data, and detect a jitter of a transmission path according to a level combination of a plurality of monitoring signals. The semiconductor system may also include a second semiconductor device configured to generate the plurality of monitoring signals of which the level combination is changed according to phase differences between an internal clock generated through the transmission path for transmitting the clock and a plurality of divided clocks obtained by dividing the frequency of the clock.
