Product profile 1.1 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. All TMDS lines are protected by an impedance-matched diode configuration that minimizes impedance discontinuities caused by typical shunt diodes. The enhanced 60 mA overcurrent / overvoltage linear regulator guarantees HDMI-compliant 5 V output voltage levels with up to 6.5 V inputs. The DDC lines use a new buffering concept which decouples the internal capacitive load from the external capacitive load for use with standard Complementary Metal Oxide Semiconductor (CMOS) or Low Voltage Transistor-Transistor Logic (LVTTL) I/O cells down to 1.8 V. This buffering also redrives the DDC and CEC signals, allowing the use of longer or cheaper HDMI cables with a higher capacitance. The internal hot plug detect module simplifies the application of the HDMI transmitter to control the hot plug signal. All lines provide appropriate integrated pull-ups and pull-downs for HDMI compliance and backdrive protection to guarantee that HDMI interface signals are not pulled down when the system is powered down or enters Standby mode. Only a single external capacitor is required for operation. 1.2 Features and benefits     HDMI 2.0 and all backward compatible standards are supported 6.0 Gbps TMDS Bit Rate (600 Mcsc TMDS Character Rate) compatible Supports Ultra High-Definition (UHD) 4K (2160p) 60 Hz display modes Impedance matched 100  differential transmission line ESD protection for TMDS lines (10 ). No Printed-Circuit Board (PCB) pre-compensation required  Simplified flow-through routing utilizing less overall PCB space  DDC capacitive decoupling between system side and HDMI connector side and buffering to drive cable with high capacitive load (> 700 pF/25 m) IP4788CZ32 NXP Semiconductors DVI and HDMI interface ESD and overcurrent protection  All external I/O lines with ESD protection of at least 14 kV, exceeding the IEC 61000-4-2, level 4 standard  Hot plug detect module  CEC buffering and isolation, with integrated backdrive-protected 26 k pull-up  Robust ESD protection without degradation after repeated ESD strikes  Highest integration in a small footprint, PCB level, optimized RF routing, 32-pin HVQFN leadless package 1.3 Applications  The IP4788CZ32 can be used for a wide range of HDMI source devices, consumer and computing electronics:  High-Definition (HD) and Standard-Definition (SD) Blu-ray and DVD players  Set-top box  PC graphic card  Game console  HDMI picture performance quality enhancer module  Digital Visual Interface (DVI) 2.
