<p>PURPOSE:To realize data transmission with high reliability at a higher speed by suppressing the roundness of the waveform of a loopback synchronizing signal to be a reference to data from a slave circuit section to a master circuit section in the data transmission system in which digital data are transferred between a master circuit section and a slave circuit section by applying a synchronous signal regulating a transmission timing and a reception timing to a bus from the master circuit section. CONSTITUTION:The slave circuit section 1 and the slave circuit section N send data to a reception data bus 9 synchronously with a loopback synchronizing signal correcting the duty ratio of the synchronous signal from a bus at a bus termination section 4. The master circuit section 1 receives the data from the reception data bus 9 and uses a master circuit section ES(elastic storage) 1h to fetch the data, thereby absorbing a phase difference between the loopback synchronizing signal and the synchronous signal in the inside of the master circuit section 1.</p> |
