Parallel RGB LCD Interface


The layout requirements depend on the pixel clock and therefore on the required display 

resolution. The requirements below can be greatly relaxed if lower resolutions such as VGA 

640x480 are used. The maximum length restrictions are defined due to electromagnetic radiation 

problems associated with the parallel interface. From the timing perspective, the trace length of the 

interface is not limited.
