Display interfaces

3.14.8.1

DisplayPort

In addition to the LVDS and DSI ports, a multifunctional HDMI/DP module is available. The following display specifications can be
used with it:

•

HDMI 2.0a

•

Display port 1.3

•

Embedded Display Port 1.4

On the MBa8x, the interface is implemented as DisplayPort as described in the i.MX8 QM/i.MX8 QXP Hardware Developers Guide.

The series capacitors of 100 nF on the data lines are placed close to the module connector. ESD protection diodes are placed
