P16 Connector
P4 REAR I/O
MEZZANINE FRONT I/O
P15 is the primary XMC connector
8 Gigabit differential pairs are provided
(Operating data rate between 480 Mb/s and 6.6 Gbit/s)
System Management (XMC provides hardware definition information read
by the external controller using IPMI commands and I2C serial bus
transactions.)
3.3V power (4 pins at 1A/pin)
3.3V auxiliary power (1 pin at 1A/pin)
Variable power (5V or 12V) (8 pins at 1A/pin)
114 pin Samtec ASP-103614-05 connector complies with ANSI/VITA 42.3-
2006
P16 secondary XMC connector
8 Gigabit differential pairs are provided
(Operating data rate between 480 Mb/s and 6.6 Gbit/s)
38 standard user I/O are also available (Example design uses as 19
differential LVDS pairs)
P4 Rear I/O interface: 64-pin female receptacle header (AMP 120527-1 or
equivalent). This connector provides 64 rear I/O connections.
The rear I/O P4 PMC connector connects directly to banks 25 and 35 of the
FPGA. Bank 25 and 35 Vcco pins are powered by 2.5 volts and thus will
support the 2.5 volt IOStandards. Refer to the Virtex-6 SelectIO User Guide
(available from Xilinx) for more information on the IOStandards available.
The example design defines the rear I/O with 2.5 volt LVDS.
Maximum Recommended Clock Rate…….150MHz (6.7ns clock period)
Vcco Supply Voltage ……………..…………...….2.5 volt
VOH Output High Voltage………….……….…..1.602 volt

VODIFF Differential Output Voltage …….…350m volt typical
VOCM Output Common Mode Voltage.....1.25 volt typical
VIDIFF Differential Input Voltage…………....100m volt minimum
VICM Input Common Mode Voltage…..……0.3 volt min, 1.2 volt typical,
2.35 volt max
This XMC module uses the 150 pin Samtec connector part number QSS-075-
01-L-D-A which mates with the mezzanine module connector part number
QTS-075-02-L-D-A-K and the Acromag Virtex 6 EDK module for external USB,
JTAG, and 13 differential I/O or 26 single ended user signals.
