Abstract

This document describes how to setup the demonstration board ADC1443D/53D DB with the Xilinx Kintex-7 KC705 development board.

Overview

The ADC1443D/53DWO Evaluation board is available in 4 versions: ADC1443D125WO-DB; ADC1443D160WO-DB; ADC1453D250WO-DB, ADC1159D250WO-DB. HMSC-FMC adaptor board is required to easily interoperate with Kintex-7 FMC connector.

3. Board goal and general description

The ADC1443D/53DxxxWO/DB board along with Xilinx KC705 development board are aimed to provide a full and complete set to evaluate and demonstrate the ADC1x43D/53D series, analog to digital converters, compliant with JESD204B JEDEC serialization standard.

 The ADCs

The board embeds 2 dual ADC devices with option for each ADC to receive a separate external clock input.

Each ADC is dual channel and needs to be fed with single-ended input ( from SMA connector).

 Power supplies

The board embeds a 5V power supply connector.

 Downloading the FPGA bit file

The FPGA code, in the form of a bit file, requires to be downloaded via the KC705 external JTAG connector.

To download the Kintex-7 bit file, ISE Design Suite 13.3 or later is required from Xilinx, or at a minimum the Xilinx ChipeScope Pro 64-bit version tool.

The FPGA is responsible for de-serializing the serial stream coming From the ADC, according to the JESD204B standard.

LED 7

Since we have 2 dual ADC on the board, each with 2 lanes, the HSDC_SW_ADC_4.exe application allows to configure the FPGA and to choose which channel, ADC, lanes we want to acquire.

The FPGA is accessible via the same USB-to-SPI interface on the ADC board.

LED Information from the FPGA are available on the KC705 board

LED 7, when lighted, signals that the JESD204B link is operational. LED5 and LED6 are toggling when FPGA receiver is getting a clock from ADC board. Once the FPGA has decoded the Serial stream, It is stocked into a size variable internal

memory ( from 4K to 64k) and could be uploaded via SPI-to-USB to the HSDC_SW_ADC_4.exe application and displayed as an FFT with all relevant information extracted.

An HSMC-to-FMC connector adapter makes it possible to connect the ADC1443D/53DWO demo board to the Xilinx KC705 board. A FMC High Pin Count (HPC) connector is required.

 USB interface

The USB interface acts like a programming interface. The main chip is an FTDI FT2232D that interface the USB Physical layer to the SPI

interface for the Two ADCs and the clock generator. The Board comes with the HSDC_SW_ADC_4.exe application that controls all these

components via USB.
