Orin root port & endpoint isolator

Hi NVIDIA team

In the Orin design guide “figure 6-4” shows

1.Isolators between RP&EP means two orin system need to isolated? even GND ?
2.if two Orin module on the same PCB ,isolate is necessary?

  1. It is to isolate the power supply of two orin, no need to isolate GND.
  2. Yes.
