USB2.0 PHY
Overview
The USB2.0 PHY IP is a complete physical layer (PHY) IP solution designed for low power and peak performance. The USB2.0 IP implements a High-Speed USB 2.0 transceiver for use with either host and device function controllers. Compliant with the UTMI+ level 3 specification, the USB2.0 PHY IP integrates mixed-signal circuits to support High-Speed data rate at 480Mbps and is backward compatible to Full-Speed (12Mbps) and Low-Speed (1.5Mbps) data rates. Targeting mobile and consumer product applications, the USB2.0 PHY IP also supports the supplementary USB Battery Charging specification.
