EasyPlug™ CompactPCI Backplane

Design Elements

Power Distribution

The Elma Bustronic EasyPlug CPCI backplane series features the 47-pin Positronic power connector. The 3U

and 6U cPCI versions are standardly with the power connectors in a vertically oriented position. The 9U cPCI are

standardly with the power connectors in a horizontally oriented position.

Signal Layout

The Elma Bustronic design conforms to the PICMG basic specification 2.0 R3.0 and basic Hot Swap specifications

2.0 R2.0. Some versions comply with the PICMG 2.5 R 1.0 Computer Telephony and/or PICMG 2.16 Packet

Switching specifications. A minimum stub length is utilized in routing and interconnecting to the signal traces. Our

design techniques avoid crosstalk and noise caused by inadequate ground and power.

Jumpering

Jumpers can be installed to close a circuit. The backplane has labeled areas for jumper installation. The following

applies to all of Elma Bustronic’s CompactPCI and H.110 backplanes in 2-8 slot sizes. Configurations with 2-5

slots have an addition jumper consideration, the M66EN# jumper.

64-EN# Jumper

If the jumper is installed, 64-EN# P2-B5 (see Hot Swap specification, PICMG 2.1) is ground, and 64-bit boards

will initialize for 64-bit operation. If the jumper is not installed, 64-EN# isopen, and 64-bit boards will initialize for

32-bit operation.

2-5 Slot Backplane Only

M66EN# Jumper

If the jumper is installed M66EN# P1-D21 is ground and the backplane operates in 33MHz mode. If the jumper

is not installed M66EN# is bussed and the backplane operates in 66MHz mode.
