ABSTRACT:
Provided is a disconnection and short detecting circuit capable of detecting disconnection and short of a signal line transmitting a differential clock signal. A differential buffer part DB1has a first comparator to compare a non-inverting clock signal inputted from a PADI and an inverting clock signal inputted from a PADR; a second comparator to compare a non-inverting clock signal and a reference potential Vref; and a third comparator to compare an inverting clock signal and the reference potential Vref. Their respective outputs are defined as Y, YI and YR, respectively. If the signal line of either a non-inverting clock signal or an inverting clock signal is disconnected, or short-circuited to a grounding potential VSS of a logical value Low, the logical values outputted from the second and the third comparators are equal for a long period of time in one cycle of the non-inverting clock signal or the inverting clock signal. Thereby, if a second D-flip-flop circuit F2anegates an output signal [CD], it is able to judge that disconnection or short occurs.
