Patent ID: 8081094

Claim:
A signal transmission system comprising: first parallel signal wirings; second parallel signal wirings; a serializer unit comprising: a plurality of parallel signal input terminals connected to the first parallel signal wirings; a serial conversion unit constructed to convert parallel signals input from the plurality of parallel signal input terminals into a serial signal; and a serial signal output unit constructed to output the converted serial signal; a deserializer unit comprising: a serial signal input unit constructed to input the serial signal output by the serial signal output unit of the serializer unit; a parallel conversion unit constructed to convert again the serial signal input from the serial signal input unit into the parallel signals; a plurality of parallel signal output terminals constructed to output the converted parallel signals to the second parallel signal wirings; and a transmission line constructed to connect the serializer unit and the deserializer unit, wherein one of the first parallel signal wirings is branched off into a plurality of branch wirings different from the first parallel signal wirings, the branch wirings and the first parallel signal wirings are connected to the parallel signal input terminals, and when each of the signals input from the branch wirings is converted by the serial conversion unit, the signal is converted into the serial signal so as to be temporally continuous with the signal input from the one of the first parallel signal wirings.
