USB3.1/3.0 PHY & Controller
USB3.1/3.0 PHY & Controller
The Innosilicon USB3.1/3.0 PHY is a highly programmable module that processes high-speed serial data into parallel data compatible with the PHY Interface for USB3.1/3.0 standard from Intel. The PHY supports USB3.0 SuperSpeed (5Gb/s) physical layer specifications.

Streamlined production testing is supported through BIST, multiple loopback modes, and boundary scan. Its modular nature is flexible, ensuring a PHY combination that is able to support the latest in C-type connector configurations while including all the I/Os and ESD in a single drop-in block. As with all Innosilicon IPs, our USB 3.0/3.1 solution is fully customizable to meet your specific needs.
