CompactPCI ® PICMG 2.8
PXI Backplane
Instrumentation Extensions to CompactPCI
PICMG 2.8 defines a pinout of the J2 connector for use in instrumentation
systems based on CompactPCI.
The defined pins would be used to allow multiple modules to synchronize and
precisely time the execution of their operations.
The instrumentation specification would use the allowance by the core
CompactPCI specification for implementing other functions on J2 (rear panel
I/O definition of J2 with sub-buses).
An important goal sought by this proposed committee is also to provide the
highest degree of interoperability with standard CompactPCI products
including those that implement the 64-bit pinout version of J2.
Hartmann Electronic has been a successful developer and vendor of
CompactPCI backplanes using the PXI extension for a number of years.
Shielded high-speed layout designs guarantee optimal, synchronized timing
and interference-free operation.
Mezzanine solutions enable us to implement back­planes with the most
compact dimensions possible.
Specifications include:
• 3 U/6 U
• 33 MHz/66 MHz
• 32-bit/64-bit
• 2 to 14 slots
• with/without Rear I/O

PXI Backplane 3 U
Left-hand system slot, variant LA
32 bit
mit Rear I / O
ohne rear I / O
This design has a slot pitch of 4 units to implement a backplane with the most
compact dimensions possible in 19“ card racks.
Power is supplied via screw connections and terminal bars.
Variants available:
• 32-bit
• 32-bit with rear I/O in all slots
• V(I/O) = 3.3 V or 5 V
• 33 MHz
Backplanes with more than 8 slots come with a PCI to PCI bridge.
The 8-slot backplanes are equipped with on-board Schottky barrier diodes
across from the system slot to guarantee optimal reliability and transfer
characteristics. For this reason, the 8-slot backplane is 14 mm longer than the
non-8-slot variants.

CompactPCI ® PICMG 2.0 R 3.0
PXI Backplane 3U
left-hand system slot, variant LD
In the Professional variant, the power supply via P47 power connector has
been extended by the ATX connector used in the PC world.
Screw connections for all voltages are additionally available.
The V(I/O) voltage can be changed in a simple manner with this variant.
Connectors for external connection of the JTAG bus and IPMB bus are
also assembled.
Therefore this backplane is an excellent choice for individual system designs.
Variants available:
• 32-bit
• 32-bit with rear I/O (with/without geographic addressing)
• 64-bit
• V(I/O) = 3.3 V or 5 V
• 33 MHz/66 MHz (≤ 5 slots)
