General Description

The IP4788CZ32 is designed to protect High-Definition Multimedia Interface (HDMI) transmitter host interfaces.

It includes HDMI 5 V overcurrent / overvoltage protection, Display Data Channel (DDC) buffering and decoupling, hot plug detect, backdrive protection, Consumer Electronic Control (CEC) buffering and decoupling, and 14 kV contact ElectroStatic Discharge (ESD) protection for all external I/Os, far exceeding the IEC 61000-4-2, level 4 standard.

The IP4788CZ32 incorporates Transmission Line Clamping (TLC) technology on the high-speed Transition Minimized Differential Signaling (TMDS) lines to simplify routing and help reducing impedance discontinuities.

Overview

HVQFN32 IP4788CZ32 DVI and HDMI interface ESD and overcurrent protection, DDC/CEC buffering, hot plug detect and backdrive protection Rev.
