IP4776CZ38 Fully integrated HDMI interface with level shifter, ESD and backdrive protection Rev. 6 7 January 2011 Product data sheet 1. General description The IP4776CZ38 is designed for HDMI host-interface protection. The IP4776CZ38 includes level shifting for the DDC channels and backdrive protection for HDMI as well as high-level ESD protection diodes for the TMDS signal lines. The level shifting function is required when the receiver operates at a supply voltage lower than the external devices to protect the I/Os against overvoltages. The IP4776CZ38 contains four N-channel MOSFETs to provide this level shifting function. Furthermore, all TMDS intra-pairs are protected by a special diode configuration offering an ultra low line capacitance of 0.7 pF only. These diodes provide protection to downstream components from ESD voltages up to 8 kV contact according to the IEC 61000-4-2, level 4 standard. 2. Features and benefits Pb-free and RoHS compliant, Dark Green Integrated high-level ESD protection, level shifting and backdrive protection All TMDS lines with integrated rail-to-rail clamping diodes with downstream ESD protection of 8 kV according to IEC 61000-4-2, level 4 standard Matched 0.5 mm trace spacing Bidirectional level shifting N-channel FETs provided for DDC clock and data channels TMDS lines with 0.05 pF matching of capacitance between the TMDS pairs Ultra low line capacitance of 0.7 pF per channel HDMI 1.3 compliant Backdrive protection 38-pin TSSOP lead-free package 3. Applications The IP4776CZ38 is designed for HDMI receiver and transmitter port protection, level shifting and backdrive protection e.g.: TV Graphics card Set-top box DVD Digital media adapter Game consoleIP4776CZ38 NXP Semiconductors Fully integrated HDMI interface with level shifter 4.
