SDVO
A Serial DVO connection is supported with hardware revision CE 4.x.x or newer. The digital display channel configured
from display Pipe A in GMA500 graphics adapter is capable of driving SDVO adapters that provide interfaces to a
variety of external display technologies such as HDMI, DVI, TV-out or CRT (the maximum supported pixel clock is
160MHz). Contact your local sales representative which adapters are available.
SDVO can be used optionally via onboard flat foil connector or project based on COM Express connector replacing
unused second channel LVDS B and CRT pins.
