CompactPCI (CPCI) is the specification for an industrialcomputer bus developed by PCI Industrial Computer Manufacturers Group (PICMG). CPCI is an adaptation of the Peripheral Component Interconnect (PCI)for industrial and/or embedded applications that require a more robust mechanical form factor than Desktop PCI.Elma offers backplanes for operation at 33 MHz with2-8 slots. Backplanes with 2-5 slots are available for 66 MHz bus frequency. All Elma backplanes have 64- bit routing and are hot swap capable.

CLIMATIC

-Operating temperature 0 °C up to +70 °C-Storage temperature –45 °C up to +70 °C -Climatic conditions category to IEC 68/1:25/085/21

CPCI bridge MECHANICAL

Up to three backplanes can be connected together with the bridge. Therefore the number of slots can be increased up to 21 slots. No slots are occupied by the bridge module. -Flammability:-PCB: UL 94 V-0 -Connectors: UL 94 V-0/–1-Vibration:-According to DIN 41640 part 15: 10 Hz to 500 Hz 5 g rms-Impact (10 impacts per axis x,y,z) 50 g, 6 ms-Layerstackup 8 layers -Connector: 2 mm pitch, 7 rows,-Quality class 1 compliant to spec.

EMI filter

Elma CPCI backplanes have excellent EMI properties. They are designed in a way to allow virtually zero crosstalk and extra low HF radiation. These features are realized thanks to an optimized structure with dif- ferent types of capacitors well distributed on the entire surface of the backplane.
