Overview
PMC modules are renowned for their flexibility and versatility of use. They afford the user wide
ranging system independent solutions by means of easily interchanged or upgraded mezza-
nine add-on modules. The
PEP
CP690 has been designed to maximize the advantages pro-
vided by PMC modules in a 6U environment. Flexibility, versatility, convenience and ease of
use have been keynotes throughout the design process. The result is a board which, although
essentially a carrier for PMC modules, also includes a wide range of important features such
as a PCI-PCI bridge, Rear I/O capability and (optionally available) the ability to hotswap. Use
of the hotswap version means, of course, that all PMC modules employed on the board are ef-
fectively hotswapable.
The CP690
is a 6U non-intelligent, active CPCI carrier board with two PMC slots.
Some of the Outstanding Features of the CP690:
•
active carrier with PCI-to-PCI bridge: the primary and secondary PCI busses are capable
of being operated independently of one another
•
64/32 Bit / 33MHz PCI Bus on the CPCI and on the PMC side (a 66MHz version is under
development)
•
it supports the Interrupts INTA, INTB, INTC and INTD
•
software transparent: the non-hotswap version does not require a software driver.
•
it may be configured for 5V or 3.3V signalling on the secondary PCI bus
(PMC side)
•
it supports all the signals of the PCI Bus on its connectors Jn1 (CON6/CON10), Jn2
(CON4/CON9) and Jn3 (CON7/CON11)
•
The two Jn4 connectors CON8 and CON12 provide the possibility to implement
Rear I/O through CPCI connectors J3 and J5.
•
The connectors which connect the mezzanine board with the carrier include all the sig-
nals of a 33MHz, 64/32-bit, multi-master PCI bus, the power rails for 5V, 3.3V, V(I/O) and
other specialised signals for Board Detection.
•
A PCI-to-PCI bridge provides for coupling of the PMC side to the CompactPCI side, so
that two independent PCI busses exist. The PCI-to-PCI bridge is the INTEL 21154. It is
software transparent and consequently a software driver is not required to manage data
transfer between the PMC module and the CPCI bus.
•
The CP690 has been designed to function with all PEP CompactPCI backplanes. The
fact that the J4 connector is not present on the CP690 means that this carrier board can
also be used in systems employing an H110 backplane.
•
The secondary (PMC) side of the board has been prepared for the new 64-bit PMC mod-
ules which are now starting to become available.
