Clock pulse detecting circuit and clock pulse supply device

The invention discloses a clock pulse detecting circuit and a clock pulse supply device. The clock pulse detecting circuit comprises a plurality of first transmission components, a plurality of first exclusive-OR gates and a first AND gate, wherein each of the first transmission components can be coupled with a superior first transmission component so as to receive data output by the superior first transmission component, and transmit the received data to the input end of a subordinate first transmission component according to a local clock pulse signal. In addition, the input end of the first of the first transmission components can be coupled to a clock pulse source to receive a predetermined clock pulse signal, wherein the frequency of the predetermined clock pulse signal is less than that of the local clock pulse signal. Besides, the first input end and the second input end of a kth first exclusive-OR gate can be coupled to the output ends of a kth first transmission component anda (k+1)th first transmiss
