The Virtex-7 FPGA VC7203 Characterization Kit provides the hardware environment for characterizing and evaluating 28 GTX (12.5Gbps) transceivers of the on-board Virtex-7 V485T FPGA. The VC7203 allows evaluation of the Integrated Bit Error Ratio Test (IBERT) demonstration using either the Vivado or ISE design suites. Each GTX Quad and its associated reference clock are routed from the FPGA to a connector pad which is designed to interface with a Samtec BullsEye connector. A cable enabled with a BullsEye connector and 10 standard SMAs allows users to connect to a broad range of evaluation platforms, from backplanes and optical evaluation boards to high speed test equipment. Each BullsEye connector handles a full GTX Quad, four transmit/receive pairs as well as the two independent reference clocks, enabling the highest level of flexibility in testing custom applications.
