CompactPCI Backplanes
General
General and technical Information
The CompactPCI bus is compatible
with the PCI bus known from the
PC world as far as the electrical
specifications are concerned.
The mechanical specifications were
adapted to the commonly used
Euro-board plug-in system in the 19”
card rack. Therefore this bus is also
suitable for industrial purposes.
Previously unattained signal speeds
supported by the layout technology
developed by Hartmann Elektronik
guarantee more stability and
reliability for assemblies operating in
the limit range.
The backplanes manufactured
by Hartmann Elektronik are
distinguished by a completely novel
energy buffering feature which
works across the entire frequency
range.
This feature guarantees improved
reliability thanks to more stable
supply voltages directly at the slot in
conjunction with fluctuating loads.
Chassis GND connection
A continuous electrically conductive chassis GND surface is located in the area where the bus board is mounted on the card rack. An M3 screw connection is available to connect the chassis ground. By installing a connecting bracket or terminal bar, the chassis GND can be connected to GND in a low-resistance star arrangement.
JTAG connector
A separate 6-pin connector for JTAG
boundary scan is implemented
on
the backplane.
Faster, simpler system initialization
and testing by means of the JTAG
bus even in the completely mounted
state are achieved by direct access
via an additional connector
on the
backplane.
Utility connector
The special signals to the power supply unit and external LEDs are routed to separate plug-in connectors on the backplanes. Depending on the backplane type, either a 10-pin or a 14-pin connector is used.
ATX connector
The ATX power supply connector
used in the PC world is integrated in
some backplane
variants.
This results in a highly efficient and
economic solution for supplying
power to the backplane via ATX
connectors and for the wiring of
fans and drives.
