ADV7619 CSC 422 -> RGB

Hi all!

I'm developing with adv7619, what I use to convert video (DVI/HDMI) signal to TTL for a fpga chip. I need Color Space Conversion.

Could somebody turn on the NOT automatic CSC, for instance: YUV444 -> RGB or YUV422 -> RGB?

I tried several combinations of these register (INP_COLOR_SPACE, RGB_OUT) values, but the output has wrong color always.

Input is test generator with 1080p60 YUV444

Output is a fpga what does support RGB only.

Is there a working register configuration for this feature?

Thank you in advance!!

    Hi,

     Please make sure with below i2c writes for auto CSC,

        98 02 F7 ;  Auto CSC, RGB out, Set op_656 bit
        98 03 40 ;  24 bit SDR 444 Mode 0

    Manual CSC:
    MAN_CP_CSC_EN :If MAN_CP_CSC_EN is set to 1, the CP CSC is forced into the enabled state. By default the CP CSC will be automatically enabled in the case that either a color-space conversion or video-adjustments (hue, saturation, contrast, brightness). For more details,Please refer section CP CSC Selection in ADV7619 Reference Manual in Page106 at https://ez.analog.com/video/w/documents/773/adv7619-design-support-files.Reference i2c script also available in the same path.
