ESD protection for ultra high-speed interfaces
6. Application information
The devices are 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), careful consideration should be given to
basic high-speed routing guidelines, impedance matching, and signal coupling.
Basic application diagrams for the ESD protection of an HDMI interface are shown in
Figure 10
and Figure 11.
