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.
