Abstract
An apparatus and method of reducing pixel clock jitter in a raster scanner having a oscillator which generates a pixel clock signal and a start of scan sensor for generating a start of scan signal, includes the generation of an inverted pixel clock signal and an inverted start of scan signal. Based on which of the pixel clock signal or the inverted pixel clock signal has a rising edge closer to the start of scan signal, one of the pixel clock or inverted pixel clock signal is selected to replace the original pixel clock signal. Further selections are prevented from occurring until a subsequent start of scan signal is detected.
