2P2 PMC Module Slot User I/O
In addition to the standard PMC I/O, 64 bits of configurable user I/O are provided
from the VME P2 connector directly to the PMC 1 and PMC 2 Module slot posi-
tions. All 64 bits may be routed to PMC 1, leaving 0 bits of user I/O for PMC 2.
Alternatively, 32 bits may be routed to PMC 1 and 32 bits to PMC 2. In the latter
case, PMC 1 will utilize the upper VME P2 signals—VME P2 A[32..17] and VME
P2 C[32..17]—while PMC 2 will utilize the lower VME P2 signals—VME P2
A[16..1] and VME P2 C[16..1]. The signals are available on the J1004 connector of
PMC slot 1 and the J1104 connector of PMC slot 2. If all 64 bits of user I/O are
routed to PMC slot 1, it utilizes all 64 signals of the VME P2 connector. In this case,
all 64 signals are available on the J1004 connector of PMC slot 1.
1.2.3.1 2P2 PMC Module Slot Pinouts
This section provides the pinouts of the 64 PMC User I/O signals that can be brought from
PMC Module
Slot 1
and
Slot 2
to the VME P2 connector of the 2P2 PMC Carrier Board.
Figure 1-5
shows the pin orientation of the 2P2 PMC Module Slot connector used to
install PMC Modules onto the top side of the circuit board (USPIIe, USPIIe-USB,
USPIIe-Gb, USPIIIi, or USPIIIi-OPT).
