• Difference between AD9434-500EBZ and AD9434-FMC-500EBZ

    We need to build a mix-signal system with a input from ADC over 100MSPS, and the converted data needs to be processed by FPGA.

    The evaluation board AD9434-FMC-500EBZ satisfies our requirements, but the we find that we might not be able to buy it from…

  • Programming AD9434 SPI settings on AD9434-500EBZ eval board

    Does anyone have any experience programming the SPI interface on the AD9434 (or similar) eval board? I am a relative newbie at this, so I very well may have missed something obvious.

    I am trying to talk to the eval board directly as part of a prototyping…

  • AD9434 termination


    My customer is interfacing the AD9434 and Altera Arria II FPGA but there are two methods of termination suggested - unless I am missing something!

    1. Standard LVDS Termination: 3-resistor transmitter, 1 resistor receiver termination.

      This is used…
  • AD9434 difficulties

    Hello ADI support:

    I am using the AD9434 ADC in a chemistry measurement system.  The AD9434 output is LVDS into Altera FPGA, but FPGA side is non-terminated (See Schematic Page 13 below).

    SiTime Oscillator SiT9107AC-23FH33E500.000000 drives AD9513, strapped…

  • AD9434

    We have an application that I think the AD9434 would be ideal for if I'm interpreting the data sheet correctly.  We need to have a 500MSPS ADC in an application where the ADC sits in a very low power mode, but a "trigger event" wakes up the ADC in…

  • AD9434 FFT template

    I am using the AD9434 on the  an capturing a 600 MHz signal (on the HSC-ADC-EvalC board with 500 Msps capability), while using a 320 MHz clock for the ADC.

    For additional background I have calculated, based on the input impedance to the ADC and available…

  • About AD9434

    Hi there, I have a question about AD9434.

    According to Figure 34. Analog Input DC Equivalent Circuit,

    I see the ESD diode, and just wonder how much current is accepted.

    Please tell me the allowable current for these diodes.

    I think 5mA or less?



    Hello, I'm using AD9434 to get a signal with duty, but there exist a lot of noise that fill the all 12 bits even no signal input.

    I don't config any register and use the SDR mode to collect the signal with clock 320MHz. When I input a low voltage…

  • AD9434 Test




    Please tell me the register setting for transmitting the test pattern with the AD9434.


    Instead of EVB, SPI transfer is performed and the value is written to the internal address.

    Looking at the data sheet, TestIO is prepared,
    After once flowing…

  • AD9434 Analog Input Issues


    we actually have started a design with the AD9434, but i'm a littel confused about some points in the datasheet:

    Figure 43 shows a AD9434 with an AC-coupled input  with two 200Ohm resistors feeding CML Voltage to the analog inputs on the AD9434…
