IP4786CZ32: DVI and HDMI interface ESD and overcurrent protection, DDC/CEC buffering, hot plug detect and backdrive protection
The IP4786CZ32 is designed to protect High-Definition Multimedia Interface (HDMI)
transmitter host interfaces. It includes HDMI 5 V overcurrent / overvoltage protection,
Display Data Channel (DDC) buffering and decoupling, hot plug detect, backdrive
protection, Consumer Electronic Control (CEC) buffering and decoupling, and ±12 kV
contact ElectroStatic Discharge (ESD) protection for all I/Os, exceeding the
IEC 61000-4-2 level 4 standard.
The IP4786CZ32 incorporates Transmission Line Clamping (TLC) technology on the
high-speed Transition Minimized Differential Signaling (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 enhanced 60 mA overcurrent / overvoltage linear regulator guarantees
HDMI-compliant 5 V output voltage levels with up to 6.5 V inputs.
The DDC lines use a new buffering concept which decouples the internal capacitive load
from the external capacitive load for use with standard Complementary Metal Oxide
Semiconductor (CMOS) or Low Voltage Transistor-Transistor Logic (LVTTL) I/O cells
down to 1.8 V. This buffering also redrives the DDC and CEC signals, allowing the use of
longer or cheaper HDMI cables with a higher capacitance. The internal hot plug detect
module simplifies the application of the HDMI transmitter to control the hot plug signal.
All lines provide appropriate integrated pull-ups and pull-downs for HDMI compliance and
backdrive protection to guarantee that HDMI interface signals are not pulled down if the
system is powered down or enters Standby mode. Only a single external capacitor is
required for operation.
