DisplayPort 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.
The first Digital Display Interface is carried out directly on a standard
DisplayPort Connector, CN22, type WINNING p/n WDPE-20F3L1BU3
or equivalent, with the pinout shown in the following table.
The remaining two Digital Display interfaces coming from the COM
type Jameco
Electronics p/n MDPC-S-RA-KT-TR or equivalent, with the pinout shown in
the following tables in this page
All these connectors can be used directly as a Multi-Mode Display Port connector, i.e. they can
be used also for HDMI/DVI devices by using passive external adapters.
DDI/DDIx_PAIR0-: DDI Interface #x Differential Pair #0. Can be used as Display Port
differential pair #0 or TMDS (HDMI) differential pair #2.
DDI/DDIx_PAIR1-: DDI Interface #x Differential Pair #1. Can be used as Display Port
differential pair #1 or TMDS (HDMI) differential pair #1.
DDI/DDIx_PAIR2-: DDI Interface #x Differential Pair #2. Can be used as Display Port
differential pair #2 or TMDS (HDMI) differential pair #0.
