• AD9254 input impedance

    we want to run simulations with AD9254 in Genesys and we need to know the input
    impedance @ 86MHz (or at a frequency close to this). Could you please send me
    this info ?

     

    We don’t have specific S-parameters for the AD9254, but the input architecture…

  • ad9254

    When I was doing an experiment, I found that if I give the ad9254 sample clock interface a continuous high level, logically speaking, dco should have no level change, but it is indeed changing. I don’t know what’s going on. (I found it using quartus logic…

  • ad9254

    I have an ad9254 development board with two ad9254 chips integrated on it. When I use it, I find that when I give the same sampling clock (two sampling clocks are separated by a power divider) to two ad9254 chips , The initial phase values they collected…

  • ad9254 pipeline delay(latency)

    hi

    I would like to ask, the twelve-period delay mentioned here refers to the period interval of the sampling clock, or the first twelve rising edges of the DCO are meaningless data

  • AD9254 About Sampling speed

    Hi,

    I have a question.
    Please give me an answer.

    The AD9254 has AVDD (analog power supply) and DRVDD (digital power supply).

    The two have different input voltage ranges,
    I want to use both at 1.8V.

    The data sheet has
    Only the characteristics when A VDD …

  • AD9254 ADC replacement

    Hi,

    We are presently using AD9254 ADC for our Digital Pre-distortion application.

    For our new application, the sampling speed need to be increased to 200MSPS.

    AD9254 supports upto 150MSPS. Is there a pin to pin replacement for AD9254, so that we can use…

  • EVAL-AD9254 gerber files

    Hi,

    We have selected AD9254 for our Digital Pre Distortion (DPD) application and is in the process of PCB layout design.

    It would be useful, if you could share the PCB layout of the evaluation board for AD9254.

  • Dies of "AD9254" and "AD9254S"

    Dear Sir/Madam,

      I know that "AD9254" is a commercial grade ADC and "AD9254S" is a space grade ADC.

      My question is,  are the dies of AD9254 and AD9254S same or different?

     

    THANKS!
