Abstract
A hierarchical data transmission system outputs a high speed second data train by step-by-step multiplexing a plurality of first data trains. A first signal processing part operates at the processing speed corresponding to the first data train, a third signal processing part operates at the processing speed corresponding to the second data train, and a second signal processing part operates at the processing speed corresponding to the intermediate speed of the first data train and second data train. A first clock signal of the speed corresponding to the processing speed of the third signal processing part, a second clock signal of the speed corresponding to the processing speed of the second signal processing part by dividing the first clock signal, and a third clock signal of the speed corresponding to the processing speed of the third signal processing part are generated the first signal processing part operates in association with the third signal processing part, by dividing the second clock signal after the phase adjustment with reference to the phase information of the first clock signal.
