[1] A HIGH level on input OE_N disables only the TMDS channels.
[2] A LOW level on input DDC_EN disables only the DDC channel.
[3] OUT_Dx channels âenabledâ means outputs OUT_Dx toggling in accordance with IN_Dx differential input voltage switching.
[4] DDC channel âenabledâ means SDA_SINK is connected to SDA_SOURCE and SCL_SINK is connected to SCL_SOURCE.
[5] The HPD_SOURCE output logic state always follows the HPD_SINK input logic state.
