Intel Desktop Board DG965MQ Technical Product Specification 1.5.1.5 Advanced Digital Display (ADD2/MEC) Card Support The GMCH routes two multiplexed SDVO ports that are each capable of driving up to a 200 MHz pixel clock to the PCI Express x16 connector. The SDVO ports can be paired for a dual channel configuration to support up to a 400 MHz pixel clock. When an ADD2/MEC card is detected, the Intel GMA X3000 graphics controller is enabled and the PCI Express x16 connector is configured for SDVO mode. SDVO mode enables the SDVO ports to be accessed by the ADD2/MEC card. An ADD2/MEC card can either be configured to support simultaneous display with the primary VGA display or can be configured to support dual independent display as an extended desktop configuration with different color depths and resolutions. ADD2/MEC cards can be designed to support the following configurations: • TV-Out (composite video) • Transition Minimized Differential Signaling (TMDS) for DVI 1.0 • Low Voltage Differential Signaling (LVDS) • Single device operating in dual channel mode • VGA output • HDTV output • HDMI/UDI support (when used with the HD Audio Link) 1.5.2 USB The board supports up to 10 USB 2.0 ports, supports UHCI and EHCI, and uses UHCIand EHCI-compatible drivers. The ICH8 provides the USB controller for all ports. The port arrangement is as follows: • Six ports are implemented with stacked back panel connectors • Four ports are routed to two separate front panel USB headers NOTE Computer systems that have an unshielded cable attached to a USB port may not meet FCC Class B requirements, even if no device is attached to the cable. Use shielded cable that meets the requirements for full-speed devices.

1.5.1.5
Advanced Digital Display (ADD2/MEC) Card Support
The GMCH routes two multiplexed SDVO ports that are each capable of driving up to a
200 MHz pixel clock to the PCI Express x16 connector.
The SDVO ports can be paired
for a dual channel configuration to support up to a 400 MHz pixel clock.
When an
ADD2/MEC card is detected, the Intel GMA X3000 graphics controller is enabled and
the PCI Express x16 connector is configured for SDVO mode.
SDVO mode enables the
SDVO ports to be accessed by the ADD2/MEC card.
An ADD2/MEC card can either be
configured to support simultaneous display with the primary VGA display or can be
configured to support dual independent display as an extended desktop configuration
with different color depths and resolutions.
ADD2/MEC cards can be designed to
support the following configurations:
•
TV-Out (composite video)
•
Transition Minimized Differential Signaling (TMDS) for DVI 1.0
•
Low Voltage Differential Signaling (LVDS)
•
Single device operating in dual channel mode
•
VGA output
•
HDTV output
•
HDMI/UDI support (when used with the HD Audio Link)
1.5.2
USB
The board supports up to 10 USB 2.0 ports, supports UHCI and EHCI, and uses UHCI-
and EHCI-compatible drivers.
The ICH8 provides the USB controller for all ports.
The port arrangement is as
follows:
•
Six ports are implemented with stacked back panel connectors
•
Four ports are routed to two separate front panel USB headers
±
NOTE
Computer systems that have an unshielded cable attached to a USB port may not
meet FCC Class B requirements, even if no device is attached to the cable.
Use
shielded cable that meets the requirements for full-speed devices.
