A data reception device that receives scrambled and transmission data as received data and that descrambles and outputs the data after adjusting the timing with the transmitter has a descramble circuit 10 detect timing adjustment data included in a timing adjustment data set that adjusts the timing with the transmitter in the data which the descramble circuit 10 has not descrambled, and comprises an LFSR suspending signal generation circuit 9 that outputs a required number of LFSR suspending signals, after first normal timing adjustment data has been received, at the output timing of data received thereafter so as to simulate a situation as if a desired number of timing adjustment data included in the timing adjustment data set were received.
