    based on our experience, it may not pass compliance test with 6 vias, two vias should work.

    Type-c should be plug. you can not have tow receptical on both sides

    also I attached loss budget for Gen1 system.

    very hard to give suggestion since it has 6 vias in the design. Can they make changes?
  • In reply to Brian Zhou:

    are you going to change the layout?
