Functional description

The HDMI2C2-14HD is a fully integrated ESD protection and signal conditioning device for

control links and TMDS data video channels of HDMI receiver (Sink).

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 1.4 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).

The integrated TMDS links ESD protection allows a video data rate up to 10.2 Gbps,

corresponding to the maximal speed specified by HDMI standard. All video format specified

by HDMI standard (from 720p30 up to 1080p60 3D) are supported, giving maximum

flexibility to designer. All these features are provided in a single 36 leads QFN package

featuring natural PCB routing and saving space on the board.

The HDMI2C2-14HD is a simple solution that provides HDMI™ designers with an easy and

fast way to reach full compliancy with the stringent HDMI 1.4 CTS on a wide temperature

range. STMicroelectronics proposes a dual version dedicated for the Sources interfaces:

the HDMI2C1-14HD.
