2.4.3.1 Signal Description
– COM Express Connector 1 (CN1B)
Key changes in Type 6 are:
 PCI interface is no longer supported and the pins are used instead for digital display
interfaces (DDI) and two additional PCI Express lanes
 IDE (PATA) parallel interface is no longer supported and the pins are used instead for
additional transmit and receive pairs for four USB 3.0 ports. (USB 3.0 is not supported
on the ETXexpress-AI module.)
 Three dedicated DDI ports have been added. Ports 1, 2, and 3 can be configured
individually for Display Port (DP), HDMI, or DVI and port 1 can also be used for SDV0.
 SDVO is no longer supported on the PEG port. Instead SDVO is multiplexed on DDI
port 1.
