PUSB3F96

ESD protection for ultra high-speed interfaces

7.

Application information

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

data buses such as HDMI, DisplayPort, eSATA and LVDS data lines.

When designing the Printed-Circuit Board (PCB), give careful consideration to impedance

matching and signal coupling. Do not connect the signal lines to unlimited current sources

like, for example, a battery.

A basic application diagram for the ESD protection of an HDMI interface is shown in

Figure 15.
