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 XC7VX485T-3 FFG1761E FPGA. The VC7203 board schematic,
bill-of-material (BOM), layout files and reference designs are available online at the
Virtex-7 FPGA VC7203 Characterization Kit website
.
FPGA Compatibility
The VC7203 board is provided with Virtex-7 XC7VX485T-3 FFG1761E FPGA. The board
also supports 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 might not
be available in the XC7VX485T device (for example: GTX QUAD_111, GTX QUAD_112,
FMC 3, and so on).
