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.

Power 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.

th
Receiver port.
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.
