Figure 3-10 Reference circuit for USB 2.0 interface
USB_D- and USB_D+ are high speed differential signal lines with the maximum transfer rate
of 480 Mbit/s. The following rules shall be followed carefully in the case of PCB layout:
⚫ USB_D- and USB_D+ signal lines should have the differential impedance of 90±10Ω.
⚫ USB_D- and USB_D+ signal line difference must be less than 2mm in length and
parallel, avoiding the right-angle routing.
⚫ USB_D- and USB_D+ signal lines should be routed on the layer that is closest to the
ground layer, and protected with GND vertically and horizontally.
