Product Description

PCIe8LXMCX2 is part of the Dynamic Engineering PCI and XMC Compatible family of
modular I/O components. PCIe8LXMCX2 adapts 2 XMC’s to one PCIe slot.

Embedded applications frequently require real time processing coupled with special
purpose IO. With PCIe8LXMCX2’s two XMC positions; a PrXMC can be matched with
another XMC to make a high bandwidth processing node. The PrXMC can
communicate with the host for set-up, and then use the local bus to control and transfer
data with the special purpose IO card.

Special features:

• 24 lane Gen1/2 compliant Switch

• 8 lanes allocated to PCIe “gold finger” interface. 8 lanes each to the XMC’s

• Switch can store and forward locally to communicate directly between the XMC’s

• Voltage monitors, each with LED’s on plus 12V, minus 12V, plus 5V, plus 3.3V, and
switch power [1.0V]

• 10A regulator for XMC 3.3V and 5V supplies. Shunts for Delayed, not Delayed, Off

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

• Front panel connector access through PCI bracket

• User IO [Jn4 and/or Jn6] 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

• Optional Ethernet connectors to support XMC’s with Ethernet

• Optional Serial Port connectors to support XMC’s with Serial Ports

• JTAG programming support

• DIP switch to select global addressing on XMC’s

PCIe8LXMCX2 is ready to use with the default settings. Just install the XMC onto
PCIe8LXMCX2 and into the system.

Headers and TestPoints

J6 and J11 are 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, and 23 are used to select the bezel grounding option. 1-2 selects AC coupled,

2-3 selects DC coupled and open is open. J12 = PCIe Bezel. J13 = Slot 0. J23 = Slot

1.

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 switch. Usually not
needed but handy if you are doing development or want to talk through the switch to the
XMC positions.

TP1 is an optional JTAG header used to connect to XMC 0. The pin definitions are in

the silk. 1: 3.3V, 2: GND, 3: TMS, 4: TDO, 5: TDI, 6: TCK, 7: TRST

J2 & J19 control the voltage on 33,67 of P2 and P7 respectively 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 & J20 control the voltage on 34,68 of P2 and P7 respectively 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.

J16 & J17 provide the serial port connections when installed. J16 is for Serial Port 0

and J17 is for serial port 1 on XMC0. Pin 1 is TX and pin 2 is Rx. Pin 3 is a ground
reference. Standard serial connections IAW 2.15 from Pn4 when this option is installed

J10 & J18 provide the ethernet port connections when installed. J10 is for ethernet Port

0 and J18 is for ethernet port 1 on XMC0. Standard Ethernet connections IAW 2.15
from Pn4 when this option is installed

P3, 4, 6 are optional power connectors to allow for added 12V power to be used by the

PCIe8LXMCX2. 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
