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