The USB 2.0 PHY is a Hi-Speed Universal Serial Bus (USB) peripheral transceiver IP based on the Intel?USB 2.0 Transceiver Macrocell Interface (UTMI) standard. It provides the complete solution of physical layer (PHY) functionality for a Hi-Speed or full-speed USB chip. Designed to seamlessly integrate with Application Specific Integrated Circuits (ASICs) and Field Programmable Gate Arrays (FPGAs), the USB 2.0 PHY simplifies the design process and speed time-to-market. Because UTMI is a proven, standardized implementation of the transceiver, the products integrated with USB 2.0 PHY are easier to test and offer wider interoperability. The USB 2.0 PHY has a parallel, bidirectional data interface with 8/16 bits width that complies with the UTMI standard. It supports data transfer at high-speed (480 Mbps) and full-speed (12 Mbps) rates, so it can operate in USB devices of either type.
