I have a CAN network that will have 24 nodes spread over 200Meters. I was planning on using the ADuM3053 for an isolated interface.
If I just use the CAN_L and CAN_H signals to connect the nodes, What keeps the common mode under control? I am trying to avoid sending GND2 down the cable....
It seemed that a split termination on the ends (2 sixty ohm) resistors with the center connected to Vref would help but I wanted to see what others have experienced.
