Note
The conga-TR3 supports two DDI interfaces by default. A third DDI interface (optional DDI) can be supported via assembly option (customized
variant). Customized variants with 3 DDI interfaces do not support LVDS/eDP port. Additionally, they can only support two independent
HDMI/DVI displays.
The DDI interfaces support dual-mode DisplayPort. To support HDMI/DVI, an external level shifter (PTN3360D) should be implemented on
the user's carrier board.
