Product Description

PCIe8LXMCX1 is part of the Dynamic Engineering PCI and XMC Compatible family of
modular I/O components. PCIe8LXMCX1 adapts an XMC to one PCIe slot.

The PC is still a frequent host to embedded HW for development, and delivery. With
the PCIe bus overtaking PCI, XMC’s and PC’s with PCIe are becoming common. Use
PCIe8LXMCX1 to use your XMC in your PC using an x8 or x16 position.

Special features:

• Passive 8 lane Gen1/2 design

• Voltage monitors, each with LED’s on plus 12V, minus 12V, plus 5V, plus 3.3V

• 10A regulator for XMC 3.3V and 5V supplies

• Selection switch for VPWR [12V or 5V]. Option for hardwired 5V or 12V

• Front panel connector access through PCI bracket

• User IO [Pn4] available through one of two cable connectors (DIN IDC or SCSI II
compatible) Spare pins on SCSI connector can be shunt selected to power or
ground.

• Cooling cutout for increased airflow to XMC’s

• Optional Fan(s) for increased airflow

• JTAG programming support

• DIP switch to select global addressing on XMC’s

The PCIe8LXMCX1 is ready to use with the default settings. Just install the XMC onto
the PCIe8LXMCX1 and then into the system.

Headers and TestPoints

J6 is used to select the VPWR source for position 0 and 1 respectively. When the

Shunt closes 1-2 – 12V is selected. With 2-3 closed 5V is selected. FET’s are used to
provide a low impedance path from the power supplies to VPWR for each position.
Options are in place on the PCB to allow hardwired selections for clients who prefer a
fixed voltage. The headers are not installed when the fixed voltage option is in place.
With pin 2 open VPWR will be open.

J12, 13, are used to select the bezel grounding option. 1-2 selects AC coupled, 2-3

selects DC coupled and open is open. J13 = PCIe Bezel. J12 = XMC bezel.

J1 is an optional header for SMB connection. Pin 1 is data and pin 2 is clock. Both are

pulled up. 3rd party tools can be used to see the “innards” of the XMC if the bus is in
use. Usually not needed but handy if you are doing development.

TP1, TP2 are optional JTAG header/pwr used to connect to the XMC. .025” sq post

header. The pin definitions are in the silk. 1: 3.3V, 2: GND, 1: TMS, 2: TDO, 3: TDI, 4:
TCK, 5: TRST

J2 controls the voltage on 33,67 of P2 when the SCSI connector options are selected.

1-2 selects 3.3V and 2-3 selects ground on those pins. The shunt and traces are rated
for 1A. Not fuse protected.

J3 controls the voltage on 34,68 of P2 when the SCSI connector options are selected.

1-2 selects 3.3V and 2-3 selects ground on those pins. The shunt and traces are rated
for 1A. Not fuse protected.

P3 is an optional power connector to allow for added 12V power to be used by the

PCIe8LXMCX1. The PCIe gold fingers allow for about 60W of power to be consumed
by the board across all XMC voltages including power supply losses. In many cases
the power budget is more than sufficient. If your XMC requires more power please
request the optional power connectors [2x3 PC power cable common with current PC
Power supplies] to increase the 12V available. Both 12V entry points are diode coupled
to prevent the current back-feeding when an external or other supply is added.

P3: 1-3 = +12, 4-6 = GND.

DipSwitch Settings

Switch 1: Global Address Settings

Position 1-3 corresponds to XMC GA0-2. When closed the signal is ‘0’. When open the
signal is ‘1’.

Position 4 corresponds to XMC-MVR0. When closed the signal is ‘0’. When open the
signal is ‘1’.

Position 5-8 are spare

Options

Dynamic Engineering offers multiple versions of the PCIe8LXMCX1design.

In addition to the basic passive design there are options for Ethernet, Fan, Serial ports,
and minimization.

The PCIe8LXMCX1 features cooling cutouts designed to support the addition of a fan in
one or two positions for each XMC. On PrXMC's and other XMC’s with high thermal
loads the fan option is a good idea. On cards with a lower thermal profile the fan is not
needed. The fan produces 5 CFM in a small area to create a high LFM rating suitable
for most cooling requirements. The fan used has a relatively low noise rating for quiet
operation. Position 1 is closest to the PCI bezel and position 2 is closer to the XMC
connectors.

In addition the PCIe8LXMCX1 has two options for Pn4 signal routing. VME style 2x32
pin header [shown] or a SCSI style connector.

Please mix and match options, as you need them.

The “VME” connectors are oriented as shown in the photo on the cover, and the
diagram. The square pad in the photo is “A1”. The mating part number is 120-964-455
Panduit, DIN-IDCA-64CSB-TG30 Robinson Nugent, Berg also has a part which is
slightly taller.

Cables and breakouts are available from Dynamic Engineering – Please see DINterm64
and DINribn64 or HDEcabl68 and HDEterm68 products from the Dynamic Engineering
website.

Applications Guide

Interfacing

Some general interfacing guidelines are presented below. Do not hesitate to contact the
factory if you need more assistance.

Installation

The XMC is mounted to the PCIe8LXMCX1 prior to installation within the chassis. For
best results: with the PCIe bracket installed, install the XMC at an angle so that the
XMC front panel bezel penetrates the PCIe bracket then rotate down to mate with the
XMC [PnX] connectors.

There are four mounting locations per XMC. Two into the XMC mounting bezel, and
two for the standoffs near the XMC bus connectors.

Start-up

Make sure that the "system" can see your hardware before trying to access it. Many
BIOS will display the PCI devices found at boot up on a "splash screen” with the
VendorID and CardId for the XMC installed and an interrupt level. If the information is
not available from the BIOS then a third party PCI device cataloging tool will be helpful

Watch the system grounds. All electrically connected equipment should have a fail­safe common ground that is large enough to handle all current loads without affecting
noise immunity. Power supplies and power consuming loads should all have their own
ground wires back to a common point.

Power all system power supplies from one switch. Connecting external voltage to
the PCIe8LXMCX1 when it is not powered can damage it, as well as the rest of the host
system. This problem may be avoided by turning all power supplies on and off at the
same time. This applies more to the XMC’s installed onto the PCIe8LXMCX1 than the
PCIe8LXMCX1 itself, and it is smart system design when it can be achieved.

Embedded Solutions Page 11

Construction and Reliability

The PCIe8LXMCX1 is constructed out of 0.062 inch thick high temp RoHS compliant
FR4 material. Cooling cutouts have been designed into the product for improved air
flow to the XMC sites. The components on the PCIe8LXMCX1 are tied into the internal
power planes to spead the dissipated heat out over a larger area. This is an effective
cooling technique in the situation where a large portion of the board has little or no
power dissipation.

A fan option is available for high thermal load XMC’s or for a chassis with a lack of air
circulation.

Surface mounted components are used. The connectors are SMT for the XMC bus and
through hole for the IO.

The XMC Module connectors are keyed and shrouded with Gold plated pins on both
plugs and receptacles. They are rated at 1 Amp per pin, 100 insertion cycles minimum.
These connectors make consistent, correct insertion easy and reliable.

The XMC Module is secured against the carrier with the XMC connectors. It is
recommended, for enhanced security against vibration, that the XMC mounting screws
are installed. The screws are supplied with the XMC from the OEM. Dynamic
Engineering has screws, standoffs, blank bezels and other XMC hardware available at a
reasonable cost if your XMC was not shipped with some of the required attachment
hardware or if it has been misplaced.

Thermal Considerations

If the XMC installed has a large heat dissipation; forced air cooling is recommended.
The zero slot Fan option can provide plenty of cooling power should your XMC require
it.
