Application information

7.1 Insertion loss

The IP4309CX9 is mainly designed as an ESD protection device for high-speed interfaces

such as HDMI, DVI and USB data lines etc.

The insertion loss in a 50

 NetWork Analyzer (NWA) of two channels of IP4309CX9 is

depicted in Figure 4. The other channels behave similar as all channels contain an

identical electrical circuitry.

The insertion loss measurement configuration of a typical 50

 NWA system for

evaluation of the IP4309CX9 is shown in Figure 3. It was measured using a test

Printed-Circuit Board (PCB) utilizing laser-drilled micro-via holes that connect the

PCB ground plane to the ground pins.
