Mini DisplayPort Interface
The VL-EPH-V6 uses a Mini DisplayPort “Sink” interface at J4 to interface with the host
computer Mini DisplayPort “Source” connector. VersaLogic cable VL-CBR-2031 provides the
Mini DisplayPort to Mini Display port connection.
DisplayPort consists of the following interfaces:
Main Link – transfers high speed isochronous video and audio data.
Auxiliary channel – used for link management and device control. The Extended Display
Identification Data (EDID) is read over this interface.
Hot Plug Detect – this signal alerts the PCH when a device is connected.
The VL-EPH-V6 supports Main DP Link operation with one or two lanes. Table 4 lists the
pinout of the VL-EPH-V6 Mini DisplayPort connector.
