The Intel Atom E38xx processor series contains an integrated graphics engine with advanced
2D/3D graphics, video decode and encode capabilities, and a display controller. The Hawk
supports one LVDS display.
LVDS Flat Panel Display Connector
The integrated LVDS flat panel display in the Hawk is an ANSI/TIA/EIA-644-1995
specification-compliant interface. It can support 18 or 24 bits of RGB pixel data plus 3 bits of
timing control (HSYNC/VSYNC/DE) on the 4 differential data output pairs. The LVDS interface
supports a maximum resolution of 1280 x 768 (60 Hz).
The Hawk has one LVDS connector at location J4.
The BIOS Setup program provides several options for standard LVDS flat panel types. If these
options do not match the requirements of the panel you are using, contact
Support@VersaLogic.com
The +3.3V power provided to pins 19 and 20 of J4 is protected by a software-controllable power
switch (1 Amp max.). This switch is controlled by the LVDD_EN signal from the LVDS
interface controller in the CPU.
