USB3.0 PHY USB PHY

USB3.0 PHY

Overview

The USB3.0 PHY IP is a complete physical layer (PHY) IP solution designed for mobile and consumer applications. Compliant with the USB3.0 base specifications, the PHY IP integrates mixed-signal circuits to support both 2.5GT/s and 5.0GT/s data transmission rates. The USB3.0 PHY IP consists of both the Physical Media Attachment (PMA) layer and the Physical Coding Sublayer (PCS), and connects easily to either the USB MAC layer using the standard PIPE-3.0 interface.
