XTX™ - the concept

PCI Express

In addition to the 32 bit parallel PCI bus, XTX™

offers 4 PCI Express™ lanes. This allows the cus-

tomer to equip their embedded PC application

with next generation of PC performance. PCI

Express™ is a low pin count interface with maxi-

mum bandwidth per pin. This results in cost

optimization and very compact solutions with

the highest I/O performance. The scalable band-

width is 2.5 GBit/s per lane and direction.

Serial ATA Interfaces (SATA)

SATA is an enhancement of the parallel ATA there-

fore offering higher performance. As a result of

this enhancement the traditional restrictions of

parallel ATA are overcome with respect to speed

and EMI.

ExpressCard™

XTX™ supports up to two ExpressCard™ slots.

ExpressCard™ is the successor to PCMCIA. This

interface allows the use of USB 2.0 and PCI

Express™ applications as well.

High Speed USB

XTX™ offers two additional USB 2.0 ports thereby

increasing the total amount of USB ports avail-

able to 6.

LPC Bus

As a replacement to the no longer supported ISA

bus, XTX™ offers the LPC (Low Pin Count) bus. The

LPC bus corresponds approximately to a serialized

ISA bus yet with a signiﬁcantly reduced number of

signals. Due to the software compatibility to the ISA

bus, I/O extensions such as additional serial ports

can be easily implemented using the LPC bus.

Backwards Compatible to ETX

XTX™ is 100% backwards compatible to the

ETX

standard. Most customer speciﬁc carrier

boards will not require a redesign in order to use

congatec’s XTX™ modules. The additional XTX™

signals do not affect the onboard ISA functions.

The ISA bus can be implemented through the

use of a PCI-ISA bridge on the customer speciﬁc

carrier board. As an alternative to this the cus-

tomer can use the readily available XTX™ LPC

bus.

Identical Mechanics to ETX

The size (95x114 mm), the mounting, the height,

the connectors and the heatspreader are exactly

the same as deﬁned in the ETX

speciﬁcation.

Existing ETX

solutions can easily switch to the

innovative XTX™ platform without any mechani-

cal change.

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

standard. XTX™ offers

the newest I/O technologies on this proven form factor. Now that the ISA bus is being used less and less in modern

embedded applications, congatec offers different features on the X2 connector instead of the ISA bus currently

found on the ETX

platform.
