CEC line for Hdmi

The CEC ( pin J50 ) line is common for all hdmi ports ?

Hi, what do you mean “common”? CEC pin is a general pin for HDMI ports.

There is 3 Hdmi ports in the SOM , but only one CEC line.
If we want to place on PCB 3 HDMI connectors ,what will be the CEC line in each connector ?

Hi, CEC supports multi devices, please check HDMI protocol for detail.

In Jetson Xavier OEM CEC line is bidirectional 1.8V open drain.
But in schematic this line is pulled up with R549 to 3.3V .
Is it ok ?

Hi, it should be 3.3V OD, thanks for your finding, the doc will be corrected.
