2.5.3 ADD2 (Advanced Digital Display) card support
The KTQ45 board 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 card is detected, the Intel GMA X4500 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 card. An ADD2 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 colour depths and resolutions.
ADD2 cards can be designed to support the following configurations:
•
TV-Out (composite video)
•
Transition Minimized Differential Signalling (TMDS) for DVI 1.0
•
Low Voltage Differential Signalling (LVDS)
•
Single device operating in dual channel mode
•

•
