Figure 24: Reference Circuit Design for USB Type-C Interface
1. USB super-speed switch IC is powered by DC adapter. So if customers want to use USB 3.0 interface
or USB OTG function, the module serves as the host device and the DC adapter must be plugged in.
2. If customers want to use USB 2.0 interface only, the module serves as the slave device. The DC
adapter can be removed and the power supply for super-speed switch IC is not needed.
