Product Overview

The IP4787CZ32 is a DVI and HDMI interface ESD Protection Device with DDC/CEC buffering and hot plug handling and back-drive protection. It is designed to protect High-Definition Multimedia Interface (HDMI) receiver interfaces. It includes HDMI 5V power management, Display Data Channel (DDC) buffering and decoupling, hot plug drive, back-drive protection, Consumer Electronic Control (CEC) buffering and decoupling and ±12kV contact ESD protection for all external I/O's, exceeding the IEC 61000-4-2, level 4 standard. It incorporates Transmission Line Clamping (TLC) technology on the high-speed Transition-Minimized Differential Signalling (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 5V power management enables host access to the memory even if no HDMI plug is connected.
  • HDMI 2.0 and all backward compatible standards are supported
  • 6Gbps TMDS Bit rate (600 Mcsc TMDS Character Rate) compatible
  • Supports Ultra High-Definition (UHD) 4K (2160p) 60Hz display modes
  • 100R Impedance differential transmission line ESD protection for TMDS lines (±10R)
  • Simplified flow-through routing utilizing less overall PCB space
  • DDC Capacitive decoupling between system side and HDMI connector side
  • Buffering to drive cable with high capacitive load
  • Hot plug detect module
  • CEC Buffering and isolation with integrated backdrive-protected 26kR pull-up
  • Robust ESD protection without degradation after repeated ESD strikes
  • Highest integration in a small footprint, PCB level and optimized RF routing
