4.1 Overview

USB standards that reach a nominal rate of 5Gbps include: USB 3.0, USB 3.1 Gen 1, and USB 3.2 Gen 1x1. These standards use the following pins: VBUS for power, D+ and D- for differential data signals, TX+, TX-, RX+, and RX- for transmitting and receiving signals, and ground.

USB 5Gbps is used in various devices and applications. There is an external connector which puts the system at risk of a high voltage strike. This transient event can cause damage to the downstream components in the system if the system is not protected properly. The following sections discuss the ESD protection requirements and the system-level design for protecting speeds up to 5Gbps.
