1. Product profile
1.1 General description
The IP4280CZ10 is designed for HDMI interface protection. The device includes high-level ElectroStatic Discharge (ESD) protection diodes for the TMDS signal lines. Furthermore, all TMDS intra-pairs are protected by a special diode configuration offering a low line capacitance of 0.7 pF only. These diodes provide protection to downstream components from ESD voltages of up to ±8 kV contact according to IEC 61000-4-2, level 4 standard.
1.2 Features
I Pb-free and RoHS compliant, Dark Green I ESD protection for HDMI I All TMDS lines with integrated rail-to-rail clamping diodes with downstream ESD protection of ±8 kV according to IEC 61000-4-2, level 4 standard I Matched 0.5 mm trace spacing I TMDS lines with ≤ 0.05 pF matching of capacitance between the TMDS pairs I Line capacitance of only 0.7 pF per channel I 4-channel TSSOP10 lead-free package I HDMI 1.3 compliant
1.3 Applications
I The IP4280CZ10 is designed for HDMI receiver and transmitter port protection e.g.: N TVs, monitors N Notebooks and mainboard graphics cards and ports N Set-top boxes and game consoles N DVD recorders and players

7. Application information
The IP4280CZ10 is mainly designed to act as a high-level ESD protection for high-speed serial data buses such as HDMI, USB 2.0 and other LVDS data lines. Therefore, a careful printed-circuit board design with respect to impedance matching, coupling to other signals, etc. is recommended. An example showing a basic abstract view of a layout for an HDMI interface is shown in Figure 1.
