    • A transmitter 1 comprises a clock generation portion 4, FIFO portion 6, and serial signal creation portion 7. The clock generation portion 4 performs modulation by spectrum spreading of a reference clock CKref, and generates a first clock CK1 with a high modulation factor and a second clock CK2 with a low modulation factor. The FIFO portion 6 takes as inputs the first clock CK1 which has been output from the clock generation portion 4 to a data generation portion 2 and output from the data generation portion 2, a parallel data signal which has been synchronized with the first clock CK1 in the data generation portion 2 and output, and the second clock CK2 output from the clock generation portion 4, and synchronizes the parallel data signal Pdata with the second clock CK2 and outputs the parallel data signal Pdata. The serial signal creation portion 7 converts a parallel data signal PRdata into a serial data signal Sdata.
