IP4786CZ32S,118

Specialized Overview

The IP4786CZ32S is an integrated protection and interface device designed for HDMI transmitter host interfaces. It provides ±12 kV contact ESD protection per IEC 61000-4-2 level 4, overcurrent/overvoltage protection, DDC/CEC buffering, hot plug detect, and backdrive protection. The component supports HDMI 2.0 standards with a 6.0 Gbps TMDS bit rate and UHD 4K (2160p) 60 Hz display modes. It features impedance-matched 100 Ω differential transmission line ESD protection for TMDS lines with ±10 Ω tolerance. The device operates with a VCC(5V0) supply range of 4.5 V to 6.5 V and a VCC(SYS) range of 1.62 V to 5.5 V. It is housed in a 32-terminal HXQFN32 package.

Specialized Feature Summary

• Transmission Line Clamping (TLC) technology on high-speed TMDS lines simplifies routing and minimizes impedance discontinuities without requiring PCB pre-compensation.
• Enhanced linear regulator guarantees HDMI-compliant 5 V output levels with inputs up to 6.5 V while providing robust overcurrent and overvoltage protection.
• DDC buffering concept decouples internal capacitive load from external loads, allowing signal redriving for longer or higher capacitance HDMI cables.
• Integrated hot plug detect module and backdrive protection ensure signals are not pulled down during power-down or standby modes.

Specialized Applications

• Tablet and notebook PCs
• Portable Media Players
• Digital Still Cameras (DSC)
• HD and SD Blu-ray and DVD players
• Set-top boxes (STB)

Specialized Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the component meets the necessary automotive or industrial qualification standards if applicable to the target design. Ensure the supplier provides valid traceability documentation for the manufacturing batch. Cross-reference the datasheet revision to confirm compatibility with current design specifications before finalizing procurement orders.

Specialized Selection Notes

Specialized FAQ

How does the IP4786CZ32S handle impedance matching for TMDS lines?

It utilizes Transmission Line Clamping (TLC) technology with an impedance-matched diode configuration, providing 100 Ω differential impedance with ±10 Ω tolerance to minimize discontinuities.

What is the maximum ESD protection rating for the external I/Os?

All external I/O lines provide ESD protection of at least ±12 kV contact discharge, exceeding the IEC 61000-4-2 level 4 standard.

Can the device drive HDMI cables with high capacitive loads?

Yes, the DDC buffering concept decouples the internal load from the external load, allowing the device to redrive signals for cables with capacitance greater than 700 pF per 25 meters.
