The Juno r2 SoC provides a USB 2.0 interface. The interface is capable of 480Mbps.
The host controller on the Juno r2 SoC connects to an external PHY on the V2M-Juno r2 motherboard.
This PHY connects to a four-port hub that connects to four USB 2.0 user ports.
Each port can supply 1A to an external load.
The following figure shows the USB 2.0 system, the host controller, PHY, and hub.
