The component offers two bidirectional buffers, integrating signal conditioning dynamic pull-up on DDC bus for maximum system robustness and signal integrity. These buffers embed also a protection to prevent from connector backdrive current from connector. ENABLE IC function is available to sense 5 V power supply presence from HDMI connector. On top of 5 V sensing, Enable IC can be used to switch off our device even if 5V IN is present. All these features are provided in a single 10 bumps WLCSP package featuring natural PCB routing, cost optimization and saving space on the board. The HDMI2C2-5F2 is a simple solution that provides HDMI designers with an easy and fast way to reach full compliance 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 link against ESD strikes and EMC issues.
