IP4776CZ38
Fully integrated HDMI interface with level shifter, ESD and
backdrive protection
Rev. 02 — 18 September 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.
