• AD9284 pinout

    I am looking at the pinout for the AD9284, and it only has one set of data pins.  The evaluation board schematic has a totally different pinout. To be more specific, the functional block diagram on the first page of the data sheet shows "channel A" differential…

  • AD9284 Virtex 5 interface

    I'm developing a AD9284, dual channel fpga based data capture system. In this, I connect the inputs of the AD9284 to the FPGA & capture the data in the fpga fabric using IDDR instance. I'm combining the 2 outputs of the IDDR, storing in a FIFO and transmitting…

  • AD9284 default mode problem

    Hi Dear,

    I am using AD9284 with the interface of adl5380 demodulator. I tried to work in default mode of AD9284. I have checked I and Q outputs of demodulator and everything was fine there. When i checked digital outputs of AD9284, I could not see the…

  • ADA4937-1 drive AD9284

    Hi there,

    My customer is designing ADA4937-1 to drive AD9284 for his project. He follow AD9284-250EBZ schematic design, however there are some questions.

    1) In EVB circuit, ADA4937-1 IN+ & IN- are swapped compared to Fig19 in AD9284 DS. Is there any…

  • PN9 Sequence for AD9284

    Dear Forum,

     

    I am testing an FPGA interface to an AD9284 ADC. One of the test modes for the AD9284 is to generate a PN 9 sequence. I had tried to generate PN sequence using MATLAB. I want to verify it once.
     

    I have a couple of questions :

     
    1) Is it…

  • Using ADA4930-1 with AD9284

    Dear all,

    I have a single-ended unipolar input signal of 0V to 5V (50 ohms source resistance) connected to the non-inverting input of the ADA4930-1.

    The ADA4930-1 is powered by single-supply 5V and has input common-mode voltage range of 0.3V to 2.8V.

  • HSC-EVALCZ AD9284 ucf file

    Hello,

    I'm trying to develop an AD9284 based data catpure application using a virtex 5 board. Can someone provide me the reference ucf file for the same using HSC-EVALCZ so that I can have it as a cross-reference for my design ?

    Thank you

  • Using AD9284 eval board with ZC706

    Hello all!

    Could you explain - is it possible to use AD9284 evaluation board with CVT-ADC-FMC-INTPZB and ZC706, not assembled HSC-ADC-EVALCZ (link 1, link2)?

    Thanks!

  • AD9284 A、B通道数据输出问题(感谢回答)?

    1、单独使用A通道或者B通道输入时,采样输出正常,但是单独使用B时输出有毛刺影响。但是同时对A、B两路输入时,输出完全不正常,请问这是什么原因造成的呢?当同时输入模拟输入A、B两路时,如何通过D7~D0来提取出采样后的AB两路数据呢?

    2、不使用SPI模式,VREF的电压是输出吗?有啥影响吗?VCM是输出吗?

  • AD9284 - Can i swap positive and negative pin of one of the ADC block?

    Hi,

    I am using AD9284 dual ADC in conjunction with driver ADA4937-2 for one of the IQ receiver. I am facing difficulty in routing the outputs of driver to the ADC deferentially without changing the layer. Is it recommended to swap the inputs of one of…
