3U compact PCI backplane with 11 slots

October 2003 Industrial Computer Hardware

The 173972 Erni backplanes are used in Compact PCI computer systems, permitting hot-swapping and meeting EMC requirements. Its high-performance features make it ideally suited for telecom, datacom, and industrial applications like CNCs robotic controls, and video image processing. The inherent limitations of Compact PCI are minimised by the use of a PCI-to-PCI bridge. This backplane may be used to implement a two-bus multiprocessor system if equipped with a non-transparent module.

* Form factor 3U dimensions: (LxH): 283,5 mm -0,3 X 128,7-0,3 mm.

* 11 slots, 10 peripheral slots.

* Two cPCI bus segments bridged with Intel 21154 transparent bridge.

* Four slots in primary segment 66 MHz bus operation capability - full 64-bit implementation.

* Seven slots in secondary segment with 33 MHz clock 32-bit implementation.

* Six slots with I/O capability.

* AB-shrouds with guides for safe mating of rear I/O transition modules.

* Fully shielded 10 layer PCB - for best EMC characteristics.

* Decoupling of supply voltages.

* V(I/O) selectable - 3,3 or 5 V.

* Controlled impedance of 65 Ω - stripline technology.

* PICMG 2.0 R3.0 and PICMG 2.1 R1.0 Hot-swap features.

* IEC 61076-4-101 and PICMG 2.0 R3.0 connectors.

* Two connectors for fans - 12 V supply.

* One connector for drives 5 V 12 V supply.

* Power supply via: DIN style M connector - PICMG 2.11 R1.0 alternatively via 20 pin ATX connector.

* Secure separation between hazardous voltages in mains supply and SELV circuit - IEC 950.

* Optional connector for system management bus IPMB - PICMG 2.9.

Custom and semi-custom designs based on our standard backplanes are possible in various configurations.
