CVBS to LVDS converter

Hello, I would like to create a converter that will allow you to connect analog cameras (CVBS) with TFT eg G121X1-L01 (LVDS). Thanks in advance for any information, I salute Thomas

    This is not a trivial task.

    Firstly CVBS is interlaced video, second PAL/NTSC resolutions are in the 720x480/576 range (square pixel sampling can produce 640 instead of 720 pixels), third most video decoders output in the YUV color space not the RGB color space.

    In order to connect to this specific LCD you need to de-interlace, up-convert to 444 instead of 422, scale, convert color space then serialize to LVDS.

    The 'simplest' way is to use a processor such as the DM355 coupled with an LVDS serializer and video decoder but I expect this will be more expensive/larger than you are expecting.

    BR,

    Steve
