2.3.9 CompactPCI Connectors J1 and J2
The CP308 provides two CompactPCI connectors, J1 and
J2, with the following functionality:
• J1: 32-bit CompactPCI interface with PCI bus
signals, arbitration, clock and power
• J2: arbitration, clock and optionally either rear I/O
interface functionality or 64-bit termination
The CP308 is designed for a CompactPCI bus architecture
and the board is capable of driving up to seven
CompactPCI slots with individual arbitration and clock
signals.
The CompactPCI standard is electrically identical to the
PCI local bus. However, these systems are enhanced to
operate in rugged industrial environments and to support
multiple slots.
2.3.9.1 CompactPCI Connector Keying
CompactPCI backplane connectors support guide lugs to
ensure a correct polarized mating (3.3 V or 5 V V(I/O)
coding).
The CP308 supports universal (3.3 V and 5 V) PCI V(I/O)
signaling voltages with one common termination resistor
configuration. Therefore, the CP308 can be inserted in
both, 3.3V and 5 V CompactPCI systems and provides it-
self no guide lug.
