Introduction
Description
The VL-EPH-V6 module provides a rugged converter from standard mini-DisplayPort video
output to LVDS (Low Voltage Differential Signaling) display panel output. The VL-EPH-V6
enables system designers to utilize their existing LVDS video panels with the latest embedded
computer video output (mini-DisplayPort).
As with all VersaLogic products, the VL-EPH-V6 supports OEM applications where high
reliability and long-term availability are required. From application design-in support, to the 5+
year production life guarantee, and a full 5-year warranty, the VL-EPH-V6 provides reliable
video conversion for demanding applications.
The VL-EPH-V6 is compliant with both DisplayPort v1.2 and DisplayPort v1.1.

Introduction
VL-EPH-V6 Reference Manual 2
Cautions
ELECTROSTATIC DISCHARGE
CAUTION:
Electrostatic discharge (ESD) can damage circuit boards, disk drives, and other
components. The circuit board must only be handled at an ESD workstation. If an
approved station is not available, some measure of protection can be provided by
wearing a grounded antistatic wrist strap. Keep all plastic away from the board, and do
not slide the board over any surface.
After removing the board from its protective wrapper, place the board on a grounded,
static-free surface, component side up. Use an antistatic foam pad if available.
The board should also be protected inside a closed metallic antistatic envelope during
shipment or storage.
EARTH GROUND REQUIREMENT
CAUTION:
All mounting standoffs should be connected to earth ground (chassis ground). This
provides proper grounding for EMI purposes.

Hardware Assembly
The VL-EPH-V6 can be secured to the host board using two hardware standoffs on the corner
mounting holes. These standoffs attach to the host using pan head screws. Standoffs and screws
are available as part number VL-HDW-105 (metric thread) or VL-HDW-106 (English thread).
Figure 3 shows a typical installation.

Notes:
1. Use 22 AWG wire for this connector
2. Use 16 AWG wire for this connector. This is particularly necessary if you are using a +3.3 V power source.

VL-EPH-V6 Reference Manual 7
Power Input Connectors
Connector J1 or J2 supplies input voltage to the VL-EPH-V6. Voltage is applied through one
connector only, not both. The VL-EPH-V6 accepts power input of either +5V ± 5% or
+3.3V ± 5%. Jumper block V1 selects the input voltage (see Jumpers on page 10).
CAUTION:
A +5V input voltage must not be applied to the VL-EPH-V6 when 3.3V mode is selected.
Doing so will damage the board.
Connector J1 is a 2-pin header for use with a plug-in latching connector. This connector is
useful for lower current LVDS panels (in the 1-3 A range).
Connector J2 is a 2-pin screw terminal, useful for higher current panels (in the 3-4 A range).
Table 2 lists the pinout of the J1and J2 connectors and shows the location of pin 1 for both
connectors.

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.
