Hello NXP,  my name is Gary Mitchell and I have an RF emissions issue with a video cable.  The video cable incorporates a converter chip PTN3361.  This is used to convert a DisplayPort signal from a PC Core to a DVI signal at the monitor end.  I am seeing a peak emission at 540MHz.  Can you identify the source of this emission? Is there any way to prevent emission at this frequency? I am runnning 1280x1024 resolution to a 19 inch monitor. I notice David Diaz Marin had posted a reference design for DP to HDMI.  Do you have any experience of RF emission testing of circuits using this part PTN3361?
