Graphics Subsystem
The graphics subsystem is part of the Intel GS45 Graphics/Memory Controller Hub (GMCH). The CCM-
BOOGIE offers two digital (SDVO) and one analog (VGA) interface. One of the SDVO ports and the
VGA interface is provided by a DVI-I graphics connector. This is both a digital and analog interface.
Recent digital input flat-panel displays are widely available with this connector style. For classic
monitors, adapters or adapter cables can be used for converting from DVI-I to the 15-pin HD D-SUB
connector.
A special display transmitter chip is used to convert Intel's proprietary, PCI express based SDVO
interface to the differential DVI signals. The SiI1362 (Silicon Image) transmitter uses PanelLink® Digital
technology to support displays ranging from VGA to UXGA resolutions (25 - 165Mpps) in a single link
interface.
The 2
nd
SDVO port is fed to the on-board connector J_SDVO. Expansion boards like CCO-CONCERT
feature the display transmitter and provide a 2
nd
DVI channel via a pure digital DVI-D connector.
Further more J_SDVO offers the possibility to gain access to the VESA standard interface called
DisplayPort (DP) on future EKF expansion boards.
As an option, the CCM-BOOGIE can be equipped with an ordinary HD D-Sub 15-lead connector (VGA
style). This connector is suitable for analog signals only, so the PanelLink transmitter is not stuffed
with this option. Nevertheless also flat-panel displays can be attached to the D-Sub connector but
with minor reduced image quality.
Independent from the video connector actually in use, DVI or VGA, the VESA DDC 2B standard is
supported. This is a two-wire serial bus (clock, data), which is controlled by the GMCH and allows to
read out important parameters, e.g. the maximum allowable resolution, from the attached monitor.
In addition, DDC Power (+5V) is delivered to either connector. A resettable fuse is stuffed to protect
the board from an external short-circuit condition (0.75A).
Graphics drivers for the GS45 can be downloaded from the Intel web site.
