Abstract:
1. A method of transmitting data from a multimedia source, the method comprising: generating a transmission clock signal that has a first frequency by multiplying a reference clock signal that has a second frequency that is different than the first frequency; multiplying the generated transmission clock signal to generate a pixel clock signal that has a third frequency that is different than the first and second frequencies; and outputting the transmission clock signal at the time serial data of the multimedia source is transmitted, wherein multiplying the generated transmission clock signal to generate the pixel clock signal that has the third frequency that is different than the first and second frequencies comprises: passing the generated transmission clock signal through a first multiplication path that includes at least one multiplier and/or divider circuit to generate a first potential pixel clock signal; passing the generated transmission clock signal through a second multiplication path that includes at least one multiplier and/or divider circuit to generate a second potential pixel clock signal; and generating the pixel clock signal by selecting one of the first potential pixel clock signal and the second potential pixel clock signal as the pixel clock signal based on a color depth of video data that is to be transmitted by the multimedia source.
