Hello Lily,

Are you using UR913Q or 913A? The part number tag says 913A but the schematic shows 913Q

Best Regards,

Casey

Hello Lily,

The EMC interference should depend strongly on your system level design including layout, camera enclosure, cable grounding scheme, etc. Can you share anything regarding the total system design? I don't see any specific problem with your schematic.

Best Regards,

Casey
