SN65DSI86 test pattern, color space, and DSI breakout board q's

Dan Andersen

  • Is there a default test pattern that can be kicked out without any input to the DSI port?
  • If 4K, 60Hz, 18bpp, video is put into the DSI ports of the IC, is the eDP output also going to be 4K, 60Hz, 18bpp? Is there any color space conversion that could happen to make the output 4K, 60Hz, 24bpp for a 4K, 60Hz, 18bpp input?
  • Do we have a DSI breakout board available, Samtec HDR-128291-XX? Or is this required to purchase elsewhere?

Thanks,

Dan

    Hello Dan,

    The DSI86 has a color bar generator which does not require the DSI interface and it determined by the values programmed into the Video Registers. Note that all color bars will be transmitted at a 60-Hz frame rate.

    The SN65DSIx6 transmits either 18bpp or 24bpp over the DisplayPort interface based on the DP_18BPP_EN bit.
    When this bit is cleared and 18 bpp is being received on DSI interface, the SN65DSIx6 performs the following translation of the 18 bpp into 24 bpp: new[7:0] = {original[5:0], original[5:4]}. When the DP_18BPP_EN bit is set and 24 bpp is being received on DSI interface, the SN65DSIx6 performs the following translation of 24 bpp to 18 bpp: new[5:0] = original[7:2].

    I will send you an EVM request form via email.
