3.3.5 DisplayPort / HDMI Connector
®
According to Qseven
for video signals, that are shared between DisplayPort interface and TMDS interface. This means
®
that Qseven
CPU modules compliant to rel.2.0 can offer one of these two video interfaces,
remaining compliant to the specifications.
Depending on the CPU module used, however, only one of these two interfaces can work. For this
reason, it is given the possibility to purchase the board in two different configurations.
In case you are planning to keep the compatibility with Qseven
of HDMI displays, simply by choosing when plugging the module on the Carrier board, then you
can purchase the board with a DP+HDMI combo connector, CN3, type FREEPORT p/n 62EHDS-
30AN0-P1-D, with the following pinout (it is HDMI and Display Port standard pinout):.
