3.2.10 High-Definition-Multimedia-Interface (HDMI) Interface
The SMARC sAT30 module supports a single HDMI interface with a resolution up to 1920x1080 pixels. HDMI
signals are exposed on the SMARC sAT30 edge connector as shown below:
The Carrier board must do voltage translation for the DDC and HPD signals, as well as ESD protection on all the HDMI
signals. The Carrier board ESD protection is important as HDMI is a hot-pluggable interface. A device such as the Texas
Instruments TPD12S016 is recommended. The Kontron SMARC Evaluation Board schematic (KAI 501-146) is useful as an
implementation example.
