The USB 2.0 OTG PHY is a Hi-Speed USB peripheral transceiver IP that implements the Intel® UTMI standard. It provides a High/Full-Speed USB analog front-end with a build-in 8-bit/16-bit parallel interface, therefore, it is easy to interface with USB2.0 Device System. It can work either as a host PHY or as a device PHY, depending on the different setting from controller.
