6.1
FMC
The NetFPGA-SUME board includes a VITA-57 compatible FMC (FPGA Mezzanine Card) carrier connector. A High
Pin Count (HPC) connector is used to provide the maximum possible compatibility with a variety of commercially
available mezzanine cards. Select I/O ports on the XC7V690T are connected to all of the standard Low Pin Count
(LPC) signals on the connector, due to the limitations of the FFG1761 package. All the I/O ports connected to FMC
connector only supports 1.8V logic. All 10 differential send/receive pairs for GTX transceivers are also supported.
Please refer to the American National Standards Institute ANSI/VITA 57.1 FPGA Mezzanine Card (FMC) Standard
for additional details regarding standard FMC module and carrier requirements. Refer to Appendix B of this
document for specific I/O constraints relating FPGA pins to their associated FMC control and connector pins.
6.2
QTH
The NetFPGA-SUME board includes a Samtec 0.5 mm-pitch QSH/QTH family of high-speed board-to-board
communication. The QTH connector wires out 8 transceivers from Virtex-7 FPGAs and tested at a speed of
12.5Gbps. Please refer to

footprint, etc.
6.3
Pmod
The NetFPGA-SUME board also provides a Pmod port for peripheral extension. The Pmod port is arranged as a 2×6
vertical, 100-mil female connector that mates with standard 2×6 pin headers. Each 12-pin Pmod port provides two
