Hi there, Does anybody could share about ADUM4160 GND layout tips?
The layout depends on what you are trying to achieve. We usually recommend 4 layer boards. If you have a concern about radiated emissions, I would recommend looking at AN-1109 which uses stitching capacitance to mitigate emissions. Connection of the ground planes to the cable ground should be hard wired at one end of the cable and capacitive or resistively coupled at the other to keep the cable shield from radiating.
If you have specific questions, feel free to ask.
