SN65DSI86: eDP resolution on SN65DSI86

Part Number: SN65DSI86

Hi team,

One of our customers would like to know what the maximum eDP output resolution is If only 2 DSI lane signals connect to the input of SN65DS186?

Thanks for your support and time,

    Hello Leroy,

    It depends on the maximun DSI clock rate supported by your GPU and the desired color bit depth (18bpp or 24bpp). For example, the device support a 1680 × 1050  resolutiuon at 60 Hz and 24bpp, with a DSI pixel clock of 750Mhz and two DSI data lanes. 

    Regards

    Hi Joel,

    Thanks for detail explanation. Is there the table or the information that shows the DSI clock speed and number of lanes versus the DP resolution? From the below description I got from the customer, the system should be able to support 1920x1080p(60Hz) resolution of eDP panel with 2 lanes DSI, right? Please advised. Thanks again for your help!!

    Hello Leroy Song,

    They would need more than two lanes to support a 1920x1080p(60Hz) resolution panel.
