Function
Ground
Supply voltage (3.3 V ± 5%)
Connect to GND through a 4.7 KΩ ± 1% precision
reference resistor. Sets the output current to
generate the output voltage compliant with TMDS
Provides equalizer boost function. Set to L for
short cables and H for long cables.
External power to connect the pull-up resistor on
DDC Y ports. Connect to GND if unused.

High: 5 V power signal asserted from source to
sink and EDID is ready.
Low: No 5 V power signal is asserted from source
to sink or EDID is not ready.
External power to connect the pull-up resistor on
DDC C ports. Connect to GND if unused.
Output enable, active low
Supply voltage (3.3 V ± 5%)
Port 3 hot plug detector output. Open drain output.
Connect an external resistor according to the
HDMI specification.
