PROBLEM TO BE SOLVED: To provide a signal transfer system, in which plural signal input output sections that are mutually cascade connected are provided, data sampling margin is secured, even when the transfer speed of data signals is increased and EMI(electromagnetic interference) problems are also suppressed. SOLUTION: In each of the signal input output sections provided in the system, data signals are divided into two channels from a single channel by an input latch circuit 6Li, based on a first fundamental clock CKA. Then, the data signals divided into two channels by the circuit 6Li are made into a single channel, based on a second fundamental clock CKB, and the signals are outputted to a next stage signal input output section. Moreover, the inputted first clock CKA is outputted to the next stage signal input output section as the second fundamental clock CKB, and the inputted second fundamental clock CKB is outputted to the next stage signal input output section as the first fundamental clock CKA. |
