PUSB3FR4

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 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.
