VC707 Evaluation Board www.xilinx.com 59
UG885 (v1.4) May 12, 2014
Feature Descriptions
The 10 x 40 rows of an FMC HPC connector provides pins for up to:
• 160 single-ended or 80 differential user-defined signals
• 10 GTX transceivers
•2 GTX clocks
•4 differential clocks
• 159 ground and 15 power connections
The VC707 board FMC2 HPC connector J37 implements a subset of the maximum signal
and clock connectivity capabilities:
• 58 differential user-defined pairs (as shipped with the Virtex-7
XC7VX485T-2FFG1761C FPGA installed on the VC707 board, the FMC2 HB00-HB21
bus connections are not supported. Refer to the Virtex-7 FPGA VC707 Evaluation Kit
Master Answer Record in Appendix F: References for more information).
• 34 LA pairs (LA00-LA33)
• 24 HA pairs (HA00-HA23)
•8 GTX transceivers
•2 GTX clocks
•2 differential clocks
The FMC2 HPC signals are distributed across GTX Quads 116 and 117. Each Quad has the
VCCO voltage connected to VADJ.
Note:
The VC707 board VADJ voltage for the FMC2 HPC (J37) connector is determined by the
FMC VADJ power sequencing logic described in FMC_VADJ Voltage Control, page 72.
Signaling Speed Ratings:
• Single-ended: 9 GHz (18 Gb/s)
• Differential
• Optimal Vertical: 9 GHz (18 Gb/s)
• Optimal Horizontal: 16 GHz (32 Gb/s)
• High Density Vertical: 7 GHz (15 Gb/s)
Mechanical specifications:
• Samtec SEAM/SEAF Series
• 1.27 mm x 1.27 mm (0.050" x 0.050") pitch
The Samtec connector system is rated for signaling speeds up to 9 GHz (18 Gb/s) based on
a -3 dB insertion loss point within a two-level signaling environment.
