Detail of Function
DDC I2C data for respective HDMI receiver port.
These signals are true open drain, and do not pull to ground when power is not
applied to the device. These pins require an external pull-up resistor.
DDC I2C data for VGA port.
This signal is true open drain, and does not pull to ground when power is not
applied to the device. This pin requires an external pull-up resistor.
DDC I2C clock for respective HDMI receiver port.
These signals are true open drain, and do not pull to ground when power is not
applied to the device. These pins require an external pull-up resistor.
DDC I2C clock for VGA port.
This signal is true open drain, and does not pull to ground when power is not
applied to the device. This pin requires an external pull-up resistor.
DDC master I2C data for HDMI transmitter Port 0.
This signal is true open drain, and does not pull to ground when power is not
applied to the device. This pin requires an external pull-up resistor.
DDC master I2C data for HDMI transmitter Port 1.
This signal is true open drain, and does not pull to ground when power is not
applied to the device. This pin requires an external pull-up resistor.
DDC master I2C clock for HDMI transmitter Port 0.
This signal is true open drain, and does not pull to ground when power is not
applied to the device. This pin requires an external pull-up resistor.
DDC master I2C clock for HDMI transmitter Port 1.
This signal is true open drain, and does not pull to ground when power is not
applied to the device. This pin requires an external pull-up resistor.
5 V port detection input for respective HDMI receiver port.
Connect to 5 V signal from HDMI input connector. These pins require a 10 ohms
series resistor, a 5.1 k-ohms pull down resistor, and at least a 1 μF capacitor to
ground.
Hot plug detect output for the respective HDMI receiver port.
In MHL mode, these pins serve as the respective CTRL bus.
Hot plug detect input for HDMI transmitter Port 0.
Hot plug detect input for HDMI transmitter Port 1.
MHL cable detect 0/programmable GPIO 0.
MHL cable detect 1/programmable GPIO 1.
