ETX-DC®/ Introduction

2.3 ETX® Benefits

Embedded technology extended (ETX®) modules are very compact (~100mm square, 12mm thick), highly integrated

computers. All ETX® modules feature a standardized form factor and a standardized connector layout that carry a

specified set of signals. This standardization allows designers to create a single-system baseboard that can accept

present and future ETX® modules.

ETX® modules include common personal computer (PC) peripheral functions such as:

» Graphics

» Parallel, Serial, and USB ports

» Keyboard/mouse

» Ethernet

» Sound

» IDE

The baseboard designer can optimize exactly how each of these functions implements physically. Designers can place

connectors precisely where needed for the application on a baseboard designed to optimally fit a system’s packaging.

Peripheral PCI or ISA buses can be implemented directly on the baseboard rather than on mechanically unwieldy

expansion cards. The ability to build a system on a single baseboard using the computer as one plug-in component

simplifies packaging, eliminates cabling, and significantly reduces system-level cost.

A single baseboard design can use a range of ETX® modules. This flexibility can differentiate products at various

price/performance points, or to design future proof systems that have a built-in upgrade path. The modularity of an

ETX® solution also ensures against obsolescence as computer technology evolves. A properly designed ETX®

baseboard can work with several successive generations of ETX® modules.

An ETX® baseboard design has many advantages of a custom, computer-board design but delivers better

obsolescence protection, greatly reduced engineering effort, and faster time to market.
