XTX™ - "eXtended lifecycle for ETX®"– developed
and forced by congatec AG ®

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. The new features include new serial high speed
buses like PCI Express™ and Serial ATA®. All other signals found on con-
nectors X1, X3, and X4 will remain the same in accordance to the ETX®
standard (Rev. 2.7) and therefore the XTX™ is 100% backwards to the
ETX® standard (Rev. 2.7).  The additional XTX™ signals do not affect the
onboard ISA functions. If the customer’s application still requires the ISA
bus then a PCI-ISA bridge can be implemented on the customer specific
baseboard. The size (95x114 mm), the mounting, the height, the connectors
and the heatspreader are exactly the same as defined in the ETX® specifi-
cation. Existing ETX® solutions can easily switch to the innovative XTX™
platform without any mechanical change.
