SN65DSI86: DSI86 can support 3840 x 2160 at 30 Hz 18bpp with 4 lane MIPI DSI input

Part Number: SN65DSI86

HI ,

Let me know  SN65DS186 can support   3840 x 2160 (4K resolution ) at 30 Hz frame rate  of color depth of  18bpp  with  MIPI DSI input   4 lane . 

MY host CPU   MIPI  DSI 4 lane  support  with speed of  D-PHY 1.2  (2.5Gpbs per lane) 



  • Hi,

    Stream bit = pixel clock x bpp = 300MHz x 18 = 5.4G

    Max DSI clock frequency = stream bit / (2 x min number of DSI lanes) = 5.4 / (2 x 4) = 675MHz, below the max DSI clock 750MHz supported by the DSI86.

    So DSI86 will support 4k@30Hz at 18bpp.

    Is the CPU backward compatible with MIPI D-PHY 1.1?
