Revision
Initial Xilinx release.
Chapter 1, VC707 Evaluation Board Features: In Table 1-1, notes for J37 changed to 
Samtec ASP_134486_01. The board photo in Figure 1-2 was replaced. In Table 1-3, GPGA 
(U1) Bank 32 was deleted. A note was added about the user clock for Figure 1-10. In 
Table 1-15, FPGA pin AN1 changed to AM4 and pin AN2 changed to AM3. In SGMII 
GTX Transceiver Clock Generation, page 42, 25 MHz LVDS clock changed to 125 MHz 
LVDS clock. The Figure 1-10 title also changed from 25 MHz to 125 MHz. In Table 1-23, 
pin AR42 changed to AT42. In Figure 1-33, switching regulator supply voltage UG63 for 
MGTVCCAUX was updated. In Table 1-29, device type PTD08D021W (VOUT A) power 
rail voltage changed to 1.80V. In Table 1-32, values for rail number 3 changed. In 
Appendix C, Master Constraints File Listing, the entire listing was replaced. 
Appendix G, Regulatory and Compliance Information now includes a link to the 
Declaration of Conformity and markings for waste electrical and electronic equipment 
(WEEE), restriction of hazardous substances (RoHS), and CE compliance.

Chapter 1
VC707 Evaluation Board Features
Overview
The VC707 evaluation board for the Virtex®-7 FPGA provides a hardware environment for 
developing and evaluating designs targeting the Virtex-7 XC7VX485T-2FFG1761C FPGA. 
The VC707 board provides features common to many embedded processing systems, 
including a DDR3 SODIMM memory, an 8-lane PCI Express® interface, a tri-mode 
Ethernet PHY, general purpose I/O, and two UART interfaces. Other features can be 
added by using mezzanine cards attached to either of two VITA-57 FPGA mezzanine 
connectors (FMC) provided on the board. Two high pin count (HPC) FMCs are provided. 
See VC707 Board Features for a complete list of features. The details for each feature are 
described in Feature Descriptions, page 10.
Additional Information
See Appendix F, Additional Resources for references to documents, files and resources 
relevant to the VC707 board.
