Video (SDVO/LVDS) Interfaces

The Atom™ E6XXT CPU provides an integrated 2D/3D graphics engine, which supports video decode such
as MPEG2, MPEG4, VC1, WMV9, H.264 (main, baseline at L3 and High-profile level 4.0/4.1), and DivX*
as well as video encode such as MPEG4, H.264 (baseline at L3), and VGA. The CPU supports LVDS and
SDVO display ports, permitting simultaneous, independent operation of two displays. The video interface
features are listed in the following bullets. Refer to
Table 3-11 for the LVDS pin signal definitions.
SDVO:
•
Supports a maximum resolution of 1280 x 1024 at 85Hz (pixel clock rate up to 160MHz)
•
Supports a single channel interface through a 30-pin FPC connector
•
Supports 100MHz to 160MHz derivative clock frequency
•
Supports third-party output formats such as DVI, LVDS, HDMI, TV-Out, and VGA
•
Provides a control bus able to operate at up to 1 MHz
LVDS:
•
Supports a maximum resolution of 1280 x 768 at 60Hz (pixel clock rate up to 80MHz)
•
Supports minimum pixel clock rate of 19.75MHz
•
Supports a single channel interface through a 20-pin header
•
Supports pixel color depths of 18 and 24 bits
•
Supports 20MHz to 80MHz derivative clock frequency
Table 3-10 lists the pin signals of the SDVO FPC connector, which provides 30 pins in a single row with
0.020" (0.5mm) pitch.
