3U CompactPCI backplane with hot-swap features

10 October 2001 Computer/Embedded Technology

The 173916 Erni backplane is used in CompactPCI computer systems. 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 CompactPCI 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 nontransparent bridge module.

* Form factor 3U dimensions: H x L: 197,1 mm-0,3 x 128,7-0,3 mm.

* 8 slots, 7 peripheral slots: system slot right-hand side.

* Fully shielded 10-layer for best EMC characteristics.

* Controlled impedance of 65 Ohm - stripline technology.

* Decoupling of supply voltages.

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

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

* Clock frequency 33 MHz.

* 6 slots full 64 implementation, 2 slots 32 bit implementation.

* Rear I/O via P2 of physical slots 1 and 2.

* A and AB - shrouds with guides for safe mating.

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

* One connector for fans 12 V supply.

* Two connectors for drives 5/12 V supply.

* Optional connection via Faston or M4-screw DIN style connector PICMG 2.11 R1.0.

* Auxiliary signals accessible via headers.

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