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

PSG_4

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?

Thanks

David
