CompactPCI Bus Interfaces
The complete CompactPCI connector configuration comprises two
connectors named J1 and J2. Their function is as follows:
X
J1: 32-bit CompactPCI interface with PCI bus signals, arbi-
tration, clock and power
X
J2: has optional Rear I/O interface functionality or 64-bit ter-
mination
The board is capable of driving up to seven CompactPCI slots,
with individual arbitration and clock signals. The cPCI-3920 is not
hot-swappable but supports the addition or removal of other
boards whilst in a powered-up state.
The cPCI-3920 is designed for a CompactPCI bus architecture.
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.
