DP++ Connectors
According to COM Express specifications, Type 6 pinout defines three Digital Display interfaces (DDI), that can be used to carry out DisplayPort and TMDS
(HDMI/DVI) interface.
On MC96 Carrier board, these interfaces are carried to as many right-angle single DP connectors, supporting DP++ (so that it is possible to
connect also HDMI and DVI displays by using external adapters).
DDI1,DDI2 and DDI3 are carried out directly on standard DisplayPort Connectors, CN52,CN53 and CN54, type WINNING p/n WDPE-
20F3L1BU3 or equivalent, with the pinout shown in the following table.
