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.

Cautions

Electrostatic discharge (ESD) can damage circuit boards, disk drives, and other

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.

All mounting standoffs should be connected to earth ground (chassis ground). This
provides proper grounding for EMI purposes.

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
