2.6.3.2 VGA DAC Schematic Example
The Apalis standard features a dedicated VGA interface. Nevertheless, it is possible to add a
parallel RGB to VGA converter if an additional VGA interface is needed or a specific Apalis module
does not feature VGA output at the VGA pins. For additional information about the availability of a
dedicated VGA interface and whether it is independent from the parallel RGB interface, please
consult the applicable Apalis module datasheet.

2.6.3.3 LVDS Transmitter Schematic Example
As EMC compliance, if using the parallel RGB interface becomes problematic, it is recommended to
attach liquid crystal displays with high resolutions using a LVDS interface. LVDS also reduces
problems with long cables. The Apalis standard features a dedicated LVDS LCD interface. If the
provided LVDS interface is incompatible with the display or an additional interface is needed, a
parallel RGB to LVDS transmitter can be placed on the carrier board. Please consult the Apalis
module to determine whether the dedicated LVDS interface is independent from the parallel RGB
interface.
As there are different LVDS color mappings available, check with your display vendor on how the
RGB signals need to be connected to the transmitter.
