Микросхемы и комплектующие IP4787CZ32

Защитное устройство от ЭСР , 8 В, HVQFN, 32 вывод(-ов), 5 В, 50 мВт, IP478

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
