hi,
i have a ground and signal issues of my motor application. my motor and control unit has 10cm apart with common ground, 200v, usart, and 20v wires connected, both uart wire has many noise injected or it might caused by motor side's ground noise, therefore i would like to use digital isolator such as ISO722x to isolate both side, but the point is my ground is common and it is 10cm apart (i couldn't add more wires, so ground has to be common).
