Video 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). The CPU supports LVDS and SDVO
display ports, permitting simultaneous, independent operation of two displays. The video interface features
are listed in the following two bullet lists.
LVDS
•
Supports a maximum resolution of 1280 x 768 at 60 Hz (pixel clock rate up to 80 MHz)
•
Supports minimum pixel clock rate of 19.75 MHz
•
Supports pixel color depths of 18 and 24 bits
•
Supports 20 MHz to 80 MHz derivative clock frequency
SDVO
•
Supports a maximum resolution of 1280 x 1024 at 85Hz (pixel clock rate up to 160MHz)
•
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 1MHz
Audio Interface
The High Definition (HD) Audio controller resides in the CPU and communicates with external codec(s) on
the baseboard (such as audio and modem codecs) over the Intel HD Audio serial link. The PCH implements
a single Serial Data Output signal (AC/HDA_SDOUT) that is connected to all external codecs. Two Serial
Digital Input signals (AC/HDA_SDIN) support up to two codecs.
Ethernet Interface
The nanoX-TCR supports one Gigabit Ethernet interface. The Ethernet interface is implemented from the
82574IT Ethernet controller and provides one GLAN interface, which occupies PCI Express port 1. The
Ethernet function supports multi-speed operation at 10/100/1000 Mbps and operates in full-duplex at all
supported speeds or half duplex at 10/100 Mbps while adhering to the IEEE 802.3x flow control
specification.
The Ethernet interface offers the following features:
•
Full duplex or half duplex support at 10 Mbps, 100 Mbps, or 1000 Mbps
•
In full duplex mode, the Ethernet controller adheres to the IEEE 802.3x Flow Control specification
•
In half duplex mode, performance is enhanced by a proprietary collision reduction mechanism
•
IEEE 802.3 compatible physical layer to wire transformer
•
IEEE 802.3u Auto-Negotiation support
•
Fast back-to-back transmission support with minimum interframe spacing (IFS)
•
IEEE 802.3x auto-negotiation support for speed and duplex operation
•
3 kB transmit and 3 kB receive FIFOs (helps prevent data underflow and overflow)
•
Requires magnetics (Ethernet isolation transformer) on the baseboard
