IP4788CZ32J

Specialized Overview

The IP4788CZ32J is an integrated ESD protection and overcurrent protection device designed for HDMI transmitter host interfaces. It supports HDMI 2.0 standards with a TMDS bit rate of 6.0 Gbps, enabling Ultra High-Definition (UHD) 4K at 60 Hz. The component features impedance-matched 100 Ω differential transmission line ESD protection for TMDS lines with ±10 Ω tolerance. It includes a 60 mA overcurrent/overvoltage linear regulator that guarantees HDMI-compliant 5 V output levels with up to 6.5 V inputs. All external I/Os provide ±14 kV contact ESD protection per IEC 61000-4-2 Level 4. The device utilizes Transmission Line Clamping (TLC) technology on high-speed TMDS lines to minimize impedance discontinuities.

Specialized Feature Summary

• Incorporates Transmission Line Clamping (TLC) technology on high-speed TMDS lines to simplify routing and reduce impedance discontinuities without requiring PCB pre-compensation.
• Features DDC buffering and decoupling that isolates internal capacitive load from external loads, supporting standard CMOS or LVTTL I/O cells down to 1.8 V and driving cables with high capacitance.
• Includes an enhanced 60 mA overcurrent/overvoltage linear regulator ensuring HDMI-compliant 5 V output voltage levels even with input voltages up to 6.5 V.
• Provides robust ±14 kV contact ESD protection on all external I/O lines, exceeding the IEC 61000-4-2 Level 4 standard.

Specialized Applications

• High-Definition (HD) and Standard-Definition (SD) Blu-ray and DVD players
• Set-top boxes
• PC graphic cards
• Game consoles
• Digital Visual Interface (DVI) systems

Specialized Procurement Notes

Verify the specific suffix 'J' against official Nexperia documentation to confirm if it denotes a distinct variant or packaging option compared to the base IP4788CZ32 model. Confirm RoHS compliance status and lead-free characteristics directly from the manufacturer's datasheet before finalizing procurement specifications.

Specialized Selection Notes

Select this component for designs requiring integrated protection for HDMI 2.0 interfaces supporting 4K resolution. Ensure the system accommodates the HVQFN32 package dimensions and provides the necessary VCC(5V0) and VCC(SYS) supply rails. Verify compatibility with the required CEC standby control logic and hot plug detect configurations.

Specialized Part Context

The IP4788CZ32J belongs to the IP4788 series of interface protection devices manufactured by Nexperia. This series is engineered specifically for consumer electronics and computing applications involving digital video interfaces. The component consolidates multiple protection functions into a single small-footprint package to optimize PCB space.

Specialized Replacement Considerations

Check for direct pin-compatible substitutes within the Nexperia portfolio that offer similar TMDS protection and DDC buffering capabilities. Verify that any replacement part maintains the same HVQFN32 package outline and meets the required ±14 kV ESD protection levels.
