XTX 820 Brings ETX to the Future
Ampro’s XTX 820 Computer-On-Module (COM)
allows OEM to access the latest processor chipset
technology without a complete redesign of their ETX
baseboard. We understand how much OEMs have
invested in custom baseboards, consequently
Ampro will help to make XTX an industry standard
in order to provide the cleanest path forward for
OEMs to adopt new processors and chipsets.
Although the ETX standard does not accommodate
new high-speed serial technologies such as Serial
ATA and PCI Express, the new XTX standard
provides an extension to ETX by replacing the ISA
bus signals with four PCI Express lanes, two Serial
ATA ports, two additional USB ports, and the Low
Pin Count (LPC) bus. The LPC bus has already
replaced the ISA bus in desktop and notebook PCs
and chipsets. Access to both the PCI bus and the
LPC bus at the XTX baseboard interface gives OEMs
two options for generating the ISA bus if it’s
needed: Through a PCI-to-ISA bridge or an LPC-to-
ISA bridge on the baseboard. Unlike other COM
architectures, XTX retains support for legacy
peripherals such as serial ports, parallel port, floppy
drive, Parallel ATA (IDE), and PS/2 keyboard and
mouse.
XTX uses the same four baseboard connectors as
ETX, in the same locations, and the module holes
and dimensions are identical for seamless migration
from a mechanical standpoint. Electrically, only the
signals on one connector X2 are different (ISA bus).
For OEMs not using ISA, the XTX 820 plugs directly
into existing ETX baseboards, allowing easy access
to the latest chipset technology, graphics, and
processors plus a “bridge to the future” so that
baseboards can take advantage of PCI Express and
Serial ATA when it’s convenient for each OEM.
Other new module standards use completely
different connectors, signals, locations, and board
sizes, which causes a substantial baseboard design
immediately, even when PCI Express is not needed
in the short term.
Featuring performance up to 1.8 Gigahertz
Pentium
®
M, the XTX 820 COM retains legacy
peripherals while offering the latest high-speed
interconnect and storage technologies. The XTX 820
COM offers the next generation Intel 915GM chipset
along with a choice of 1.0GHz, 1.4GHz, or 1.8GHz
Intel processors, DDR2 400 RAM to 1GB, (6) USB
2.0 ports, both EIDE and Serial ATA interfaces,
10/100 Ethernet, PCI expansion, and RoHS
compliance. XTX modules plug into a baseboard to
allow customization of board size and shape, I/O
circuitry, connector locations, and easy migration to
higher performance modules in the future.
The XTX 820 QuickStart Kits include drivers and
Board Support Packages (BSPs) for Windows
®
XP,
Windows XP Embedded, Windows CE 5.0,
VxWorks
®
, and QNX
®
operating systems, and a full
Linux
®
2.6 distribution (Fedora™ Core 3).
The XTX 820 is also designed with full ACPI 2.0
support, including S3 suspend-to-RAM. AMI BIOS
provides full support for wake-up devices, including
LAN, keyboard, mouse, power button, and PCI or
SMBus activity. Below are the details for the ACPI
functions supported by XTX 820.
Power and Sleep States
The following information only applies if an ATX
power supply is connected to the XTX baseboard
where the XTX 820 is installed. If a non-ATX power
supply is used, then the XTX 820 is only controlled
by the Power-On/Off switch on the power supply
and the various sleep states are not available. The
ACPI sleep states are OS dependent and not
available if your OS does not support power
management based on the ACPI standard.
Power-On Switch
The Power-On switch, on or connected to the XTX
Baseboard, turns the XTX 820 and its attached
power supply to a fully On condition, if you are
using an ATX power supply and an OS that supports
sleep states. If the operating system (OS) supports
sleep states, the OS will turn off the XTX 820 and
its power supply during the OS shut down process.
Typically, the Power-On switch will also transition
the XTX 820, the XTX baseboard, and its power
supply between a fully powered on state and the
various sleep states, including a fully powered off
state. If the OS does not support sleep states, then
the Power-On switch only turns power, On or Off, to
the XTX 820 and its baseboard.
Typically, an OS that supports ACPI, also allows the
Power-On switch to be configured through a user
interface. The Power-On switch for the XTX 820
must be provided on, or connected to the
baseboard.
