The IP4786CZ32S is a DVI and HDMI interface ESD and Over-current Protection Device with DDC/CEC buffering and hot plug detect and back-drive protection. It is designed to protect High-Definition Multimedia Interface (HDMI) transmitter host interfaces. It includes HDMI 5V overcurrent/overvoltage protection, Data Display Channel (DDC) buffering and decoupling, Hot Plug Detect (HPD), back-drive protection, Consumer Electronic Control (CEC) buffering and decoupling and ±12kV contact ESD protection for all I/O"s in accordance with the IEC 61000-4-2, level 4 standard. The device 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.
● 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
