3.5.2 USB2.0 Interface Application
The reference circuit is shown in Figure 14:
Figure 14 Reference Circuit for USB 2.0 Interface
Since the module supports USB 2.0 High-Speed, it is required to use TVS diodes with
equivalent capacitance of 1pF or smaller ones on the USB_D-/D+ differential signal lines, it
is recommended to use 0.5pF TVS diodes.
USB_D- and USB_D+ are high speed differential signal lines with the maximum transfer rate
of 480 Mbit/s, so the following rules shall be followed carefully in the case of PCB layout:
