This document presents the steps to setup an environment for using the EVAL-CN0241-SDPZ evaluation board together with the Xilinx KC705 FPGA board and the Xilinx Embedded Development Kit (EDK). Below is presented a picture of the EVAL-CN0241-SDPZ Evaluation Board with the Xilinx KC705 board.

Below is presented a picture of SDP-B Controller Board with the EVAL-CN0241A-SDPZ Evaluation Board.

The circuit from the EVAL-CN0241-SDPZ board is a classic high-side current sensing circuit topology with a single sense resistor. High-side current monitors are likely to encounter overvoltage conditions from transients or when the monitoring circuits are connected, disconnected, or powered down.

The AD7920 is a 12-bit, high speed, low power, successive-approximation ADC respectively. The part operates from a single 2.35 V to 5.25 V power supply and features throughput rates up to 250 kSPS. The part contains a low-noise, wide bandwidth track/hold amplifier, which can handle input frequencies in excess of 6 MHz.

The first objective is to ensure that you have all of the items needed and to install the software tools so that you are ready to create and run the evaluation project.

• Xilinx KC705 FPGA board
• FMC-SDP adapter board
• EVAL-CN0241-SDPZ evaluation board

• Xilinx ISE 14.6.
• UART Terminal (Termite/Tera Term/Hyperterminal), baud rate 115200.
• The EVAL-CN0241 reference project for Xilinx KC705 FPGA.

• Use the FMC-SDP interposer to connect the ADI evaluation board to the Xilinx KC705 board on the FMC LPC connector.
• Connect the JTAG and UART cables to the KC705 and power up the FPGA board.

The following commands were implemented in this version of EVAL-CN0241 reference project for Xilinx KC705 FPGA board.

Commands can be executed using a serial terminal connected to the UART peripheral of Xilinx KC705 FPGA.

The following image shows a generic list of commands in a serial terminal connected to Xilinx KC705 FPGA's UART peripheral.
