describes the pin signals of the Ethernet GLAN2 interface, which consists of a two-row, 10-pin
vertical header with odd/even (1,2) pin sequence, and 0.079" (2mm) pitch.
Note: The shaded table cells denote ground.
Video Interfaces
The Core i7, 3517UE CPU provides an integrated 2D/3D graphics engine, which supports video decode
such as MPEG2, VC-1, and AVC/H.264 (main, baseline at L3 and High-profile level 4.0/4.1) as well as
video encode such as MPEG2, AVC/H.264 (baseline at L3), and VGA. The PCH supports VGA, LVDS, and
HDMI display ports, permitting simultaneous, independent operation of two displays. The CPU provides
PCIe x16 Graphics signals to the PCIe/104 connector for an external high-performance PCI Express
Graphics card or other general purpose PCI Express devices. The video interface features are listed in the
following bullets. Refer to
for definitions of the VGA pin signals and
for the LVDS
pin signal definitions. The HDMI interface is a standard HDMI micro connector, and those pin signals are
not defined in this manual. The PEG signals are part of the standard PCIe/104 interface and are not defined
in this manual.
VGA:
•
Supports resolutions up to 2048x1536 pixels at 75Hz
•
Provides integrated 340.4MHz RAMDAC with 32-bit color
•
Provides RGB output by three 8-bit DACs
•
Supports HSYNC and VSYNC output
LVDS:
•
Supports a maximum resolution of 1400x1050 at 60Hz (pixel clock rate up to 112MHz)
•
Supports minimum pixel clock rate of 25MHz
•
Supports a single channel interface through a 20-pin header
•
Supports pixel color depths of 18 and 24 bits
HDMI:
•
Supports resolutions up to 3840x2160 pixels at 30Hz
•
Supports pixel clock rates from 25MHz to 340MHz
