IP4777CZ38 DVI and HDMI interface ESD protection

The IP4777CZ38 is designed for HDMI transmitter host interface protection. The IP4777CZ38 includes DDC buffering and decoupling, hot plug detect, backdrive protection, CEC slew rate control, and high-level ESD protection diodes for the TMDS lines. The DDC lines use a new buffering concept which decouples the internal capacitive load from the external capacit.

Features

I I I I I I I I I I HDMI 1.3 compliant Pb-free and RoHS compliant; Dark Green Robust ESD protection without degradation after several ESD strikes Low leakage even after several hundred ESD discharges Very high diode switching speed (ns) and low line capacitance of 0.7 pF to ground and 0.05 pF between channel can ensure signal integrity DDC capacitive decoupling between system side and HDMI connector side and buffering to drive cable with high capacitive load (> 700 pF) Hot plug detect module CEC ringing prevention by slew rate limiter All TMDS lines with integrated rail-to-rail clamping diodes.
