IP4309CX9
HDMI octal channel low capacitive high-performance
ESD protection
Rev. 1 — 10 March 2011
Product data sheet

1. Product profile
1.1 General description
The IP4309CX9 is a 8-channel low capacitance ElectroStatic Discharge (ESD) protection
device, providing protection to downstream components from ESD voltages up to 15 kV
contact discharge and higher than 15 kV air discharge, far exceeding IEC 61000-4-2,
level 4.
The device is optimized for the protection of high-speed interfaces such as High-Definition
Multimedia Interface (HDMI), Digital Video Interface (DVI) and other interfaces requiring
very low capacitance ESD protection. In order to prevent any current backdrive into the
adjacent channel, all eight ESD protection channels are electrically separated and share
only the same ground connections.
The IP4309CX9 is fabricated using monolithic silicon technology in a single Wafer Level
Chip-Size Package (WLCSP). These features make IP4309CX9 ideal for use in
applications requiring component miniaturization, such as mobile phone handsets.
1.2 Features and benefits

7. 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.
