ADV7180-ADV7343  SFL

Hi,all,

    i used decoder adv7180 and encoder adv7343,the SFL signal is connected dircetly.

    When i set adv7180 register 0x04[1]=0,SFL output is disabled,the video output from adv7343 is OK,please see figure1;

    But when i set adv7180 register 0x04[1]=1,SFL output is enabled,the video output from adv7343 is bad,please see figure2,there is a purple stripe below the picture.

    And figure3 is the video source input to adv7180.
