VC7203 Board Features and Operation
This Chapter describes the components, features, and operation of the
VC7203 Virtex™-7 FPGA GTX Transceiver Characterization Board. The VC7203 board
provides the hardware environment for characterizing and evaluating the GTX
transceivers available on the Virtex-7 XC7V485T-3 FFG1761E FPGA. The VC7203 board
schematic, bill-of-material (BOM), layout files and reference designs are available online at

FPGA Compatibility
The VC7203 board is provided with Virtex-7 XC7V485T-3 FFG1761E FPGA. The board will
also support all device densities (i.e., XC7VX330T, XC7V585T, XC7VX690T, XC7V1500T,
and XC7V2000T devices) in the pin-compatible FFG1761, FLG1761, and FHG1761
packages. However, certain interfaces that are available in larger density devices may not
be available in the XC7V485T device (for example: GTX QUAD_111, GTX QUAD_112,
FMC 3, etc.). Unsupported interfaces are highlighted in this document.
