1-7 Versatile Media Capabilities
High Definition Audio
The High Definition Audio Controller embedded in the ICH9DO delivers up to four
codecs that can be used for different types of codecs, such as audio and modem
codecs. Operating at 3.3V or 1.5V, the embedded Audio Controller supports a
multi-channel audio stream, 32-bit sample depth, up to 192 kHz of same rate, and
can be used with a variety of microphones for input. With these versatile audio
capabilities built in, the C2SBC-Q provides the user with a state of the art audio
experience that is larger than life.
I/O Virtualization Technology (VT-d)
With the Intel ICH9DO built in, the C2SBC-Q supports I/O Virtualization Technology
(VT-d) that enables multiple operating systems and applications to run in indepen-
dent partitions. Each partition uses its own subset of host physical memory, and
behaves like a virtual machine (VM), providing isolation and protection across
multiple partitions. This feature is available when a processor that supports the
virtualization of platforms is installed on the motherboard.
1-8 Super I/O
The disk drive adapter functions of the Super I/O chip include a data separator,
write pre-compensation circuitry, decode logic, data rate selection, a clock genera-
tor, drive interface control logic and interrupt and DMA logic. The wide range of
functions integrated onto the Super I/O greatly reduces the number of components
required for interfacing with floppy disk drives. The Super I/O supports two 360 K,
720 K, 1.2 M, 1.44 M or 2.88 M disk drives and data transfer rates of 250 Kb/s,
500 Kb/s or 1 Mb/s.
It also provides two high-speed, 16550 compatible serial communication ports
(UARTs). Each UART includes a 16-byte send/receive FIFO, a programmable baud
rate generator, complete modem control capability and a processor interrupt sys-
tem. Both UARTs provide legacy speed with baud rate of up to 115.2 Kbps as well
as an advanced speed with baud rates of 250 K, 500 K, or 1 Mb/s, which support
higher speed modems.
The Super I/O provides functions that comply with the ACPI (Advanced Configura -
tion and Power Interface), which includes support of legacy and ACPI power man-
agement through a SMI or SCI function pin. It also features auto power management
to reduce power consumption.
