Functional description
The HDMI2C1-6C1 is a fully integrated ESD protection and signal conditioning device for
control stage of HDMI™ transmitters (Source).
The component offers a bidirectional buffer, integrating signal conditioning and dynamic
pull-up on DDC bus for maximum system robustness and signal integrity. 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 +5 V supplied to the cable is protected
against accidental surge current and short circuit. All these features are provided in a single
18 leads QFN package featuring natural PCB routing and saving space on the board. The
HEAC (HDMI Ethernet and Audio return Channels) function is supported, making the
component fully compliant with HDMI™ 1.4 version.
The HDMI2C1-6C1 is a simple solution that provides HDMI™ designers with an easy and
fast way to reach full compliancy with the stringent HDMI™ CTS on a wide temperature
range. STMicroelectronics proposes also a large range of High Speed ESD protections and
common mode filter (ECMF™ series) dedicated to the TMDS lanes giving the flexibility to
the designer to filter and protect these high speed video links against ESD strikes and EMC
issues. Last, a fully integrated version HDMI2C1-14HD exists, grouping equivalent control
stage functional blocks, plus the high speed ESD protection for TMDS lanes.
