• HSC-ADC-EVALDZ and AD9681

    Hi,

           about a mouth ago ,we brought an HSC-ADC-EVALDZ and EVAL-AD9681, but recent days, it sems broken.

          We follow the "Evaluation board for AD9278/AD9279 UG",  1. connect the boards to each other ;2. connect the two boards with each power…

  • AD9681 spurs in waveform - digital reset cannot solve everytime ?

    We use AD9681 8 channel with 125 MHz rate. Some channel sometimes have spurs in waveform like figure1 and sometimes perfect as figüre 2. We test all digital patterns and we get them correct always. We do digital reset(0x08->0x00, 0x08->0x03, 0x08->0x00…

  • Deserializing AD9681 LVDS Interface

    I'm using a FMC AD9681 Evaluation Board with a Genesys 2 (Kintex-7 XC7K325T-2FFG900C). I've got the SPI interface up and running, and I can successfully communicate with the ADC. Now I am trying to get the LVDS ADC Interface up and running, but I am…

  • RE: Driver program for SPI of AD9681

    Doug,

    I am interested to get this sample code too. It seems it should attached in the sample design but I didn't find much info there. I also want to know how users could use the AD9681 eval board without the FPGA codes.

  • Revision check before purchasing an EVB of AD9681

    Dear, 

    I want check the revision of AD9681-125EBZ.

    From the Wiki site of "Evaluating the AD9681 Analog-to-Digital Converter", I found below comment.

    There are two versions of the AD9681 evaluation board AD9681-125EBZ.

    The earlier version uses…

  • How to input LVDS signal at AD9681

    My customer use AD9681 and they should supply LVDS signal to AD9681 directly.

    So they need your help about how to implement input circuit of AD9681 for receiveing LVDS signals directly.

    1) Could AD9681 receive LVDS signal directly (without using additional…

  • Spurs in AD9681 Waveform

    I am using an AD9681 FMC Evaluation Board, with a Genesys 2 FPGA Board (XC7K325T-2FFG900C). I've gotten the xilinx XAPP 524 working on the board for receiving data, however I am running into an issue with the waveforms I am getting. The sine wave looks…

  • 关于AD9681输出赋值不满足LVDS电平要求问题

    各位大神,本人在使用AD9681芯片时遇到一个奇怪的问题,一共使用了12片AD9681,其中有几片AD9681输出电平(LVDS接口)不满足要求。

    具体情况如下:AD转换以后的数据通过FPGA进行数据采集,其中AD9681与FPGA直接进行直接连接,在FPGA内部进行短接100欧姆,在使用VIVADO软件进行数据显示时,有几路显示数据不更新,其他几路均有数据,通过检测数据不更新的这路AD,发现LVDS幅值VPP<200mv,同时检测其他正常通路的LVDS电平为vpp=400mv,

    之前咨询过ADI的厂家…
