    Hi,

    Have they done the electrical compliance testing with this design?

    Can you please share the datasheet for the 660158-1 ESD diode? 

    Since this design looks to be connecting between a HDMI source and a HDMI sink, R124 and R125 may not be needed since the 2k pullup should be present in the source and 47k pullup should be present in the sink. 

    Please leave R112 as NP so TMDS181 EQ will auto-adapt depends on the input loss, does this help with the display?

    Thanks

    David
