PCI Express
In addition to the 32 bit parallel PCI bus,
XTX™ offers 4 PCI Express™ lanes. This allows
the customer to equip their embedded
PC application with next generation of PC
performance. PCI Express™ is a low pin count
interface with maximum bandwidth per pin. The
scalable bandwidth is 2.5 GBit/s per lane and
direction.
Serial ATA Interfaces (SATA)
SATA is an enhancement of the parallel ATA
therefore 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.
High Speed USB
XTX™ offers two additional USB 2.0 ports thereby
increasing the total amount of USB ports
available 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.
Upgrade to XTX™
Applications which do not utilize the ISA bus can
directly upgrade to XTX modules. The signals at
connectors X1, X3 and X4 are equal to ETX
®
.
Only the signals at the X2 connector have been
redefined in order to support PCI Express, SATA,
LPC and more. Existing ETX
®
carrier boards can
easily be upgraded to take advantage of these
new and fast interfaces.
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 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 customer 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 mechanical
change.
