Application Information
To design USB3.0 link for best system level ESD performance and error free Signal Integrity is mandatory.
To bring both requirements together, the ESD protection devices has to provide excellent ESD and a very low
device capacitance. The Infineon ESD3V3U4ULC in “array” configuration, combined with a clear and straight
forward “full through” layout fulfills these requirements in the best way.
