1.1 General description

The device is designed to protect high-speed interfaces such as High-Definition

Multimedia Interface (HDMI), DisplayPort, USB, external Serial Advanced Technology

Attachment (eSATA) and Low Voltage Differential Signaling (LVDS) interfaces against

ElectroStatic Discharge (ESD).

The device includes high-level ESD protection diodes for high-speed signal lines in an

ultra small and leadless plastic package DFN2110-9 (SOT1178-1/XSON9). The extremely

small package dimensions (2.1 mm ? 1 mm ? 0.5 mm) make this product ideally suitable

for portable devices. The pinout is designed for convenient flow-through routing of

high-speed signal lines.

All signal lines are protected by a special diode configuration offering ultra low line

capacitance of 0.85 pF maximum. These diodes provide protection to downstream

components from ESD voltages up to ?12 kV contact according to IEC 61000-4-2, level 4.

1.2 Features and benefits

? System ESD protection for USB 2.0, HDMI 1.3 and HDMI 1.4, DisplayPort, eSATA

and LVDS

? All signal lines with integrated rail-to-rail clamping diodes for downstream

ESD protection of ?12 kV according to IEC 61000-4-2, level 4

? Matched 0.4 mm pitch trace spacing

? Line capacitance of 0.85 pF maximum for each channel

? Design-friendly ’flow-through’ signal routing

1.3 Applications

The device is designed for high-speed receiver and transmitter port protection:

? Portable devices

? Mobile handsets

? TVs, monitors

? DVD recorders and players

? Notebooks, mother boards, graphic cards and ports

? Set-top boxes and game consoles
