Backplane Configuration Header (J2)
On board the VGP10x is a backplane configuration header that allows the user the customize the Data Plane
interface to use two 4 lane interfaces, one upstream to the root complex (selectable) and one extra downstream to
allow for another peripheral card to be added to the system. Or it can be configured as a single 8 lane interface to
maximize the bandwidth to the XMC site.
Using two 4x PCIe interfaces enables the use of extended features such as allowing the downstream port to become
an NT (non-transparent) port that can be accessed from another root complex connected from a second host.
Effectively creating another upstream port that is accessed from either a backup host or a second host looking to
share the resources.
The PLX 8718 switch allows for system options that include bus failover schemes and redundant system support.
A wire-wrap is recommended to replace the 2mm jumper installation once the system is deployed. The jumpers are
not guaranteed to remain installed in a rugged environment.

System Management Interface
The GraphiteVPX/XMC-PMC supports an I2C slave interface on the SM0 (SCL) and SM1 (SDA) signals
connected to the VPX backplane. The I2C address of this interface is determined by the Geographic Address
lines GA0#, GA1#, and GA2#. This interface operates at 100 KHz.
There are 10K OHM pull-ups to the +3.3V_AUX supply on the I2C slave interface on SM0 and SM1.
The I2C interface contains an I2C mux device (PCA9544) to allow the user access to the XMC site or the 4
temperature sensors that are on the board edges as shown below.
Addressing the I2C Slave Interface (I2C Mux)
As stated above, the I2C slave interface uses GA0#, GA1#, and GA2# to determine its final I2C address. See
more details below. Refer to your backplane GA (Geographical Address) lines for the complete configuration
address.
The I2C address will be as such:
Bit7 BIT6 BIT5 BIT4 BIT3 BIT2 BIT1 BIT0
1 1 1 0 GA2# GA1# GA0# R/W

Writing to the I2C Slave Interface
Refer to the NXP PCA9544 for access details.
The I2C multiplexor is like a ‘gate’ to open an on board I2C bus to access one of three card side busses:
1) Bus 0 – is currently not accessible
2) Bus 1 – is a direct link with XMC sites I2C system interface
3) Bus 2 – is a link to 2 TMP101 temperature sensors on the top edge (device 1 and 2)
4) Bus 3 – is a link to 2 TMP101 temperature sensors on the bottom edge (device 3 and 4)
*Refer to the TI TMP101 datasheet for access and setup of ALERT pin interrupt to the PCA9544. A Thermal
Alert LED is accessible on the solder side of the card if a visual indicator is required.
Reading from the I2C Slave Interface
When reading from the I2C slave interface, the last value stored in the command register by a write operation
is used to determine which command to respond to. To change the command for a read operation, a new
command must be written to the command register. This is accomplished by issuing an I2C slave address byte
with the R/W# bit LOW, followed by the command byte. The master can then generate a START condition
and send the I2C slave address bute with the R/W# bit HIGH to initiate a read command. If repeated reads
from the same register are required it is not necessary to continually send the command byte. The slave I2C
interface will remember the original command value until it is changed by the next write operation.
Example XML code to open the I2C mux and access the 4 temperature sensors using the Totalphase
Aardvark™ USB to I2C controller can be provided by request.

3D STEP Models A complete 3D STEP Model file for the Conduction Cooled GraphiteVPX/XMC-PMC is available at:
http://www.connecttech.com/
The model contains mount points and thermal interface locations for a mounting a standard PMC or XMC
mounting with 10mm standoffs with both primary and secondary cooling interfaces. The Aluminum thermal
frame is anodized but is connected to CGND or Chassis Ground through the mounting holes. The PMC
standoff mounts are floating and are not connected to either CGND or Digital GND (ground).
CGND (Chassis Ground) is connected to Digital GND at one point through a 5Meg Ohm resistance, to allow
for the slow removal or drain of any stray charge.
** Please note that a ground loop is possible if the mezzanine connects any of the thermal interface mounting
screws to Digital Ground (GND) **
