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 different delay times to a reference clock to generate a multiphase clock with different phases. 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 a result of detecting the phase relation.

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.
