IP4776CZ38
Fully integrated HDMI interface with level shifter, ESD and
backdrive protection
Rev. 01 — 14 July 2006
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 over voltages. 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
I Pb-free and RoHS compliant
I Integrated high-level ESD protection, level shifting and backdrive protection
I 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
I Matched 0.5 mm trace spacing
I Bidirectional level shifting N-channel FETs provided for DDC clock and data channels
I TMDS lines with ≤ 0.05 pF matching of capacitance between the TMDS pairs
I Ultra low line capacitance of 0.7 pF per channel
I HDMI 1.3 compliant
I Backdrive protection
I 38-pin TSSOP lead-free package
3. Applications
I The IP4776CZ38 is designed for HDMI receiver and transmitter port protection, level
shifting and backdrive protection e.g.:
N TV
N Graphics card
N Set-top box
N DVD
N Digital media adapter
N Game console
