A HIGH level on input OE_N disables only the TMDS channels. A transition from HIGH to LOW at OE_N may disable the DDC channel
for up to 20 μs.
A LOW level on input DDC_EN disables only the DDC channel.
OUT_Dx channels ‘enabled’ means outputs OUT_Dx toggling in accordance with IN_Dx differential input voltage switching.
DDC channel ‘enabled’ means SDA_SINK is connected to SDA_SOURCE and SCL_SINK is connected to SCL_SOURCE.
The HPD_SOURCE output logic state always follows the HPD_SINK input logic state.
