Hi,
we use LVDS to transfer videosignals from a our camera (SN65LV1021) to a our framegrabber (SN65LV1212) over a cat5e compatible cable. The pixelclock is 27Mhz with leads to about 324Mb/s. The problem is that cable and camera are in a pretty "dirty" emc environment, motors and that sort of stuff. To get rid of the emc disturbance we have to isolate the chassis of the camera from the rest of the machine, so that the shield can run from the framegrabber over the cable to the camera, and we do not have ground (shield) loops.
The idea would be to make it more enthernet-like, to introduce transformers into the LVDS signals to have the cable decoupled. Do you think this could work and improve our design?
regards,
Wolfgang Kopp
