These signals are true open drain, and do not pull-down to ground when
power is not applied to the device. These pins require an external pull-up
resistor.

Input DDC I C Clock for respective port.
These signals are true open drain, and do not pull-down to ground when
power is not applied to the device. These pins require an external pull-up
resistor.
Input 5-V Port detection input for respective port.
Connect to 5-V signal from HDMI input connector. These signals require a
10 Ω series resistor and at least a 1 µF capacitor to ground. A 3.3 kΩ pull-
down resistor is also required for these signals in 5V standby mode. In 3.3V
standby mode, any value of 3.3K – 100K can be used.
Output Hot Plug Detect Output for respective port.
Connect to HOTPLUG of HDMI input connector.

If this signal is connected to the VGA cable then it requires a 10 ohm series
resistor and at least a 1 µF capacitor to ground. If connected to a local power
supply the resistor is not needed but a capacitor of at least 1 µF is
recommended.
