I/O
DDC I2C Data for respective HDMI receiver port. These signals are true open-drain, and do
I/O not pull to ground when power is not applied to the device. These pins require an external
pull-up resistor.
DDC I2C Clock for respective HDMI receiver port. These signals are true open-drain, and do
I not pull to ground when power is not applied to the device. These pins require an external
pull-up resistor.
Hot Plug Detect Output for the respective HDMI receiver port. In MHL mode, these pins serve
I/O
as the respective CTRL BUS.
5 V Port Detection Input for respective HDMI receiver port. Connect to 5 V signal from HDMI
I input connector. These pins require a 10 Ω series resistor, a 5.1 kΩ pull-down resistor, and at
least a 1 μF capacitor to ground.
- Reserved High
- Local Power from system. This pin requires a 10 Ω series resistor.
- Reserved Low
Local Confi guration/Status I2C Clock. Chip confi guration/status is accessed using this I2C
I
port. This pin is true open-drain, so it does not pull to ground if power is not supplied.
