5.1 Overview

USB standards that reach up to a nominal rate of 10Gbps are: USB 3.1 Gen 2, USB 3.2 Gen 2x1, USB 3.2 Gen 1x2, and USB 4 Gen 2x1. These standards use the following pins: VBUS for power, D+ and D- for differential data signals, one lane (USB 3.1 Gen 2, USB 3.2 Gen 2x1, and USB 4 Gen 2x1) or two lanes (USB 3.2 Gen 1x2) for transmitting and receiving signals (TX1/RX1, TX2/RX2), and ground.

USB 10Gbps is commonly used today, and since there is an external connection, the system is at risk of a high voltage strike. An ESD strike can enter through the connector and cause damage to the downstream components if the system is not protected properly. The following sections discuss the ESD protection requirements and the system-level design for protecting USB 10Gbps signals.
