ETX® oncept and XTXTM Extension

The ETX® concept is an off the shelf, multi vendor, Single-Board-Computer that

integrates all the core components of a common PC and is mounted onto an application

specific baseboard. ETX® modules have a standardized form factor of 95mm x 114mm

and have specified pinouts on the four system connectors that remain the same

regardless of the vendor. The ETX® module provides most of the functional

requirements for any application. These functions include, but are not limited to,

graphics, sound, keyboard/mouse, IDE, Ethernet, parallel, serial and USB ports. Four

ruggedized connectors provide the baseboard interface and carry all the I/ signals to

and from the ETX® module.

Baseboard designers can utilize as little or as many of the I/ interfaces as deemed

necessary. The baseboard can therefore provide all the interface connectors required to

attach the system to the application specific peripherals. This versatility allows the

designer to create a dense and optimized package, which results in a more reliable

product while simplifying system integration. Most importantly ETX® applications are

scalable, which means once a product has been created there is the ability to diversify

the product range through the use of different performance class ETX® modules. Simply

unplug one module and replace it with another, no redesign is necessary.

XTX™ is an expansion and continuation of the well-established and highly successful

ETX® standard. XTX™ offers the newest I/ technologies on this proven form factor.

Now that the ISA bus is being used less and less in modern embedded applications

congatec AG offers an array of different features on the X2 connector than those

currently found on the ETX® platform. These features include new serial high speed

buses such as PCI Express™ and Serial ATA®. All other signals found on connectors

X1, X3, and X4 remain the same in accordance to the ETX® standard (Rev. 2.7) and

therefore will be completely compatible. If the embedded PC application still requires the

ISA bus then an ISA bridge can be implemented on the application specific baseboard

or the readily available LPC bus located on the XTX™ module may be used. Contact

congatec technical support for details.

Lead-Free Designs (RoHS)

All congatec AG designs are created from lead-free components and are completely

RoHS compliant.

Electrostatic Sensitive Device

All congatec AG products are electrostatic sensitive devices and are packaged

accordingly. Do not open or handle a congatec AG product except at an

electrostatic-free workstation. Additionally, do not ship or store congatec AG products

near strong electrostatic, electromagnetic, magnetic, or radioactive fields unless the

device is contained within its original manufacturer's packaging. Be aware that failure to

comply with these guidelines will void the congatec AG Limited Warranty.

conga-X945/XA945 Options Information

The conga-X945 is available in five different optional variants. The conga-XA945 is
