ST HDMI2C1-14HD

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 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 (4K/2K 60fps) on a wide temperature range. 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.
