    摘要: A differential signal output device is disclosed that outputs transmission data as a differential signal. The device includes a first differential signal generation circuit that amplifies a signal representing the transmission data and generates the differential signal from the amplified signal; a dummy data generation circuit that is synchronized with a reference clock of the transmission data and generates dummy data that change only in a bit where the transmission data do not change; and a second differential signal generation circuit that amplifies a signal representing the dummy data and generates another differential signal from the amplified signal.

    摘要: A multiphase delay unit causes a different delay time to a reference clock to generate a multiphase clock having a different phase. A multiphase sampling unit samples the input signal using the multiphase clock, and outputs multiphase sampling data. A phase selecting unit detects a phase relation of the multiphase clock using the multiphase sampling data, and selects output data from the multiphase sampling data based on data obtained by detecting the phase relation of the multiphase clock.

    摘要: A comparator compares a time interval between a first synchronization signal and a second synchronization signal with a target value, and outputs an error therebetween. A frequency calculator calculates a set value of a pixel clock frequency based on the error output from the comparator, and outputs a frequency specification signal for specifying a pixel clock frequency according to the calculated set value. A frequency divider divides a high frequency clock generated by a high frequency clock generator by a frequency division ratio based on the frequency specification signal output from the frequency calculator, and generates the pixel clock.
