Important notice Dear Customer, On 7 February 2017 the former NXP Standard Product business became a new company with the tradename Nexperia. Nexperia is an industry leading supplier of Discrete, Logic and PowerMOS semiconductors with its focus on the automotive, industrial, computing, consumer and wearable application markets In data sheets and application notes which still contain NXP or Philips Semiconductors references, use the references to Nexperia, as shown below. Instead of IP4786CZ32 DVI and HDMI interface ESD and overcurrent protection, DDC/CEC buffering, hot plug detect and backdrive protection Rev. 5 24 June 2014 Product data sheet 1. Product profile 1.1 General description The IP4786CZ32 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 12 kV contact ElectroStatic Discharge (ESD) protection for all I/Os, exceeding the IEC 61000-4-2 level 4 standard. The IP4786CZ32 incorporates Transmission Line Clamping (TLC) technology on the high-speed Transition Minimized Differential Signaling (TMDS) lines to simplify routing and help reduce 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 if 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 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) HVQFN32
