6.1 Overview

USB standards that reach a nominal rate of 20Gbps are: USB 3.2 Gen 2x2, USB 4 Gen 2x2, and USB 4 Gen 3x1. These standards use the following pins: VBUS for power, D+ and D- for differential data signals, one lane (USB 4 Gen 3x1) or two lanes (USB 3.2 Gen 2x2 and USB 4 Gen 2x2) for transmitting and receiving signals (TX1/RX1, TX2/RX2), and ground.

USB 20Gbps is used in a range of devices and applications. Since there is a connection exposed to the outside world, there is a risk of a high voltage strike occurring. An transient event can cause damage to the downstream components in the system. The following sections discuss the ESD protection requirements and the system-level design for protecting speeds up to 20Gbps.
