1.8 ESD Protection Scheme for USB3.1 Second Generation Interface
USB 3.1 Gen 2 integrates Tx/Rx differential lines at speeds up to 10 Gbps. For these speeds, ESD protection of the
Capacitance must be minimized to maintain signal integrity.
Solution: The Tx/Rx line of the ESD solution for USB 3.1 Gen 2 should have a capacitance of 0.3 pF or less with
For signal integrity purposes, the operating voltage is >3.6 V. One solution is 4-channel ESD device ultra-low capacitance data line
(Tx,Rx), combined with a low capacitance 2-channel ESD device for D+/D- and a single-channel ESD device for VBUS lines.
