Question 1: Is there any recommendation for ESD diode connection.
Like differential positive signal should connect D+ pin and negative signal should connect D- pin. or we can connect any signal to any one of the ESD Protected Channel.
example below , USB_D- signal is connected to pin 1 and USB_D+ signal connected to pin 2
Question 2 : Can we connect ESD protection channels and NC pins together for straight-through routing as per the above schematic image.
