(ADV7511W)Can ADV7511W change the format to RGB from YUV422?

Hi !

Our customer are using ADV7511W for the ADAS R&D.

They are thinking to input RGB data to ADV7511W.

The question is this.


Can ADV7511W change the format to RGB444 from YUV422?


If it can , do you have a script for this?

Best regards.


  • Hi Jeyasudha.M

    Thank you for your support !

    And I wrote the wrong thing which customer trying to do.

    Our customer are trying to input YUV422 and change to RGB.

    Yes, I read the documents.

    But I thought that if our customer use ADV7511W with RGB444 to YUV422 , maybe data will lost.

    Anyway maybe the when the customer see the image they won't see deterioration of the image...


    I think YUV and YCbCr(YPbPr) is not exactly same.

    And I couldn't find YUV422 to RGB at Table 32 to 43 at the Programming guide.

    So I want make sure that ADV7511W can support YUV to RGB or not.

    As you said "any to any" , can ADV7511W support YUV422 to RGB?


    As I said, I think YUV and YCbCr is not same.

    So do you have some script for this?

    Or YUV and YCbCr is same?


    Also if ADV7511W can support YUV , I think they can use the input format at Hardware users guides Table 8 Style 2.

    At that situation, I think the timing will be Figure8.

    With my understanding , 1st Pixel will be Y/Cb(or U) and 2nd Pixel Y/Cr(or V).

    Is my understanding correct?

    Best regards

    Hi Kawa,

    As per the Hardware user guide page no 35 as reference, The CSC is designed to run at speeds up to 165Mhz, supporting resolutions up to 1080p at 60Hz and UXGA at 60Hz. With “any-to-any” color space support, formats such as RGB, YUV, YCbCr, and others are supported by the CSC.

    Also the programming guide section 4.3.7 also explains and table gives the register settings for the same.

    Did you look in to this at ADV7511W Design Support Files? I believe that it would be helpful to refer

    Best Regards,


  • HI Jeyasudha.M!

    Generally YUV is used for Analog video standards and YCbCr is used for Digital Video standards


    As per Video demystified book as reference, please see the definition of both here


    YUV Color Space
    The YUV color space is used by the PAL (Phase Alternation Line), NTSC (National Television System Committee), and
    SECAM (Sequentiel Couleur Avec Mémoire or Sequential Color with Memory) composite color video standards. The
    black-and-white system used only luma (Y) information; color information (U and V) was added in such a way that a
    black-and-white receiver would still display a normal black-and-white picture. Color receivers
    decoded the additional color information to display a color picture.
    The YCbCr color space was developed as part of ITU-R BT.601 during the development of a world-wide digital component video standard (discussed in Chapter 4). YCbCr is a scaled and offset version of the YUV color space

    For the Color space conversion, I believe this would be possible, but checking with part specialist to confirm it and whether he has any scripts for the same


    Best Regards,



  • Hi Jeyasudha.M

    I have another question.

    Can ADV7511W support QVGA by Table34?

    Best regards.
