SLLSF57A August 2022 – April 2024 TMDS1204
PRODUCTION DATA
The HDMI specification limits the DDC bus capacitance to ≤ 50-pF for both an HDMI source and sink. Therefore, care must be taken to make sure the total capacitance of all components (TMDS1204, FR4 trace, ESD, source, and sink) is less than 50-pF.
If implementing a DDC level shifter using pass gates, then the total capacitance will include all components between source or sink and the HDMI receptacle. These components include and are not limited to Source or Sink, the FR4 trace, ESD components, and TMDS1204.
