USB3.2 PHY

Overview

The Innosilicon USB3.2 PHY is a highly programmable module that processes high-speed serial data to parallel data compatible with the PHY Interface for USB3.2 standard from Intel. The PHY supports USB3.2 SuperSpeed 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, ESD in a single drop-in block. As with all Innosilicon IP, our USB 3.2 solution is fully customizable to meet your specific needs.
