The developed device has ADV7180BST48Z (input CVBS and output BT656)->FPGA(Chroma resampler -> YCrCb to RGB converter -> Deinterlacer -> Scaler (PAL 720x576 to 1024x768) ->Framebuffer-> Output to LCD (LVDS))->LCD screen.
The scheme is approximately like attached, difference in type of package type. I know that there are insignificant differences in terms of the nominal values. Everything works fine, but there is a problem with the lack of clarity of the edges on video image. We have the same system with NXP SAA7111, it has not such problem. I attached an example of compare two images.
Please, help me to resolve this problem.
If necessary, I can give an example of the initialization of i2c.
