1.2.14 Compact Mechanical Design
The MIC-3392MILS model has a specially designed copper heat sink for the proces-
sor to enable fanless operation. However, forced air cooling in the chassis is still
needed for operational stability and reliability.
The MIC-3392MILC model uses a conduction-cooled design that complies with
ANSI/VITA30.1-2002 specifications. It uses a pair of wedge locks and a single-piece
of CNC-milled aluminum alloy plate that conforms to the major IC packages on the
primary side of the PCB.
1.2.15 CompactPCI Bridge
The MIC-3392MIL uses a PLX PCI 6540 universal bridge as a gateway to an intelli-
gent subsystem. When configured as a system controller, the bridge acts as a stan-
dard transparent PCI-X-to-PCI bridge. As a peripheral controller it allows the local
MIC-3392MIL processor to configure and control the onboard local subsystem inde-
pendently from the CompactPCI bus host processor. The MIC-3392MIL local PCI
subsystem is presented to the CompactPCI bus host as a single CompactPCI device.
When the MIC-3392MIL is in drone mode, the PLX PCI 6540 is electrically isolated
from the CompactPCI bus. The MIC-3392MIL receives power from the backplane,
supports rear I/O and supports PICMG 2.16. The PLX PCI 6540 PCI bridge offers the
following features:
! PCI Interface
– Full compliance with the PCI Local Bus Specification, Revision 2.3
– Supports 3.3V or 5V tolerance I/O
! Transparent and non-transparent bridge function
! 64-bit, 33MHz-133MHz asynchronous operation
! Support for 8 Bus Masters
! Usable in CompactPCI system slot or peripheral slot
! 10-KB Buffer Architecture for PCI-X-to-PCI-X and PCI-X-to-PCI bridging and
speed conversion
! 1-KB downstream Posted Write buffer
! 1-KB upstream Poster Writer buffer
! 4-KB downstream Read Data buffer
! 4-KB upstream Read Data buffer
Please consult the PLX PCI 6540 data book for details.
1.2.16 I/O Connectivity
For the MIC-3392MIL, the front panel I/O is provided by one VGA port and two USB
ports. Its on-board I/O consists of one IDE channel to a Compact Flash socket and
one SATA channel which can be connected to a 2.5" SATA HDD. The MIC-3392MILC
model does not have a front panel or the on-board SATA HDD module because its
entire PCB is covered up by the conduction-cooled plate. For both models, the rear I/
O connectivity is available via the following CompactPCI connectors:
! J3: two Gigabit Ethernet links to the backplane for PICMG 2.16 packet switch
and two LAN ports on the RTM
! J4: two 10/100 LAN ports, one DVI-I port, two SATA ports, two USB ports, one
IDE channel and one audio channel on the RTM
! J5: one DVI-I port, one VGA interface (also available on the front panel), two
USB interfaces, one PS2 port (for keyboard/mouse), one FDD channel, one par-
allel channel, and three COM interfaces (available as RJ45 port, on-board con-
sole interface, and on-board COM interface) on the RTM
