Functional description
The HDMI2C1-14HD is a fully integrated ESD protection and signal conditioning device for
control links and TMDS data video channels of HDMI^™ transmitters (source).
The control stage provides a bidirectional buffer, integrating signal conditioning and dynamic
pull-up on DDC bus for maximum system robustness and signal integrity. The HEAC (HDMI
Ethernet and audio return channels) function is supported, making the component fully
compliant with HDMI 2.0 version. A bidirectional CEC block is integrated, able to wake-up
the application from stand-by mode (all power supply off, except the CEC power supply). All
video format specified by HDMI™ 2.0 standard like 1080p60 3D, 4K/2K 60fps are
supported, giving maximal flexibility to designers. The +5 V supplied to the cable is
protected against accidental surge current and short circuit. All these features are provided
in a single 36 leads QFN package featuring natural PCB routing and saving space on the
board.
The HDMI2C1-14HD is a simple solution that provides HDMI™ designers with an easy and
fast way to reach full compliance with the stringent HDMI™ 2.0 on a wide temperature
range. STMicroelectronics proposes a dual version dedicated for the sink interfaces: the
HDMI2C2-14HD.
