ESD protection for differential data lines

7.

Application information

The device is designed to provide high-level ESD protection for differential high-speed

data line pairs such as:

• USB 3.1

• HDMI 2.0

• Transition-Minimized Differential Signaling (TMDS)

• DisplayPort

• external Serial Advanced Technology Attachment (eSATA)

• Low Voltage Differential Signaling (LVDS)

When designing the PCB, give careful consideration to impedance matching and signal

coupling. Do not connect the protected signal lines to unlimited current sources like, for

example, a battery.

Since the SuperSpeed TX/RX lines are separated by GND or VBUS from the Hi-Speed

lines, PESD1USB3S makes it easy to achieve same signal lengths, straight routing, and

optimal positioning for ESD protection directly at the connector.
