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.

Power Input 5V Port detection input for respective port.
Connect to 5V signal from HDMI input connector. These signals require a
10 Ÿ series resistor and at least a 1 P F capacitor to ground. A 100 k Ÿ pull-
down resistor is also required for these signals.

Connect to HOTPLUG of HDMI input connector. In MHL mode, this serves
as the respective port control bus.
R4PWR5V 49 Power Input 5V Standby power or 5V power from 5
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 P F capacitor to ground. If connected to a local power
supply the resistor is not needed but a capacitor of at least 1
P
F is
recommended.
