Notes:
1. The SODIMM conforms to the General Standard Serial Presence-Detect Standard that is
contained in the JEDEC Standard JESD21-C. On the Vector, SA1 and SA0 are a logic level low.

User Interface and Display
The Vector provides two independent display interfaces. A 4-channel LVDS interface drives the
primary display, while an analog RGB output drives a secondary VGA display. In addition, the Vector
includes discrete backlight control signals and supports a 4-, 5-, or 8-wire resistive touch panel.
This section summarizes the Vector graphics display and video processing capabilities. Display
resolutions are specified at the maximum refresh rate and color depth. Higher resolutions may be
possible at lower refresh rates and color depths. This relationship is due primarily to the increased
processing bandwidth required at higher output resolutions.
LVDS Display Output
The growing demand for higher resolution displays has been meet with design limitations on the
interface between the LCD and graphics controller. Increased resolution LCDs require an increased
clock speed, a larger number of data lines, and a higher power consumption. LVDS serial data
transmission addresses these issues by providing a high-speed, low-power interface on a single pair of
wires per channel.
The Vector provides an LVDS output to drive a primary display on header
. This display
output consists of three or four LVDS data pairs, as well as an LVDS pixel clock, supporting 18-bit or
24-bit color. The default is 18-bit color.
Notes:
The LVDS signals are driven directly by the Intel SCH US15W; therefore, cable lengths
should be kept to a minimum. Eurotech recommends that cables be less than eight inches
in length. If your application requires cable lengths longer than eight inches, the Vector can
include an on-board LVDS buffer/repeater with configurable pre-emphasis as a volume
production option.
The following table summarizes the LVDS display capabilities.
