  • Comunication Tracks

    Hello All,

    Would there be any advantage on having a GND trace for example between the microcontroller and the CAN transceiver signals ( signal with frequencies higher then 20kHz for example )? Or should I make sure to have the signal on the outside on the signal and not between them ?

    Thanks

    Best Regards,

    BD

    To be noted that this is a 4 layer board and bellow this signal layer there is a GND plane

      Normally I do not route GND tracks on signal layer (occasionally there can be an exception e.g. around crystal or oscillator). However, what is important, I always try to make the clearance between neighbor tracks as big as possible. And I have not seen any problems with this technique.

        If you pay attention to Mr. Bogatins advice, you shouldnt place a gnd around traces. You only need to do is seperating traces between each other.
