• RE: ADF4158, ADF4159, ADF4169 software

    Hi FormerMember,

    I am trying to generate a FMCW waveform with EV-ADF4159EB1Z/EV-ADF4159EB3Z evaluation board. Is it possible to generate a pulse series as shown below on the EV board to trigger my ADC? Thanks.


    Hi all,

    For frequency readback, the following sequence is described in the datasheet @ ADF4169.

  • What is different between ADF4159 and ADF4169?


    I would like to know what is different between ADF4159 and ADF4169.

    According to the datasheet, ADF4169 has wide frequency range of RF bandwidth and PFD frequency but it doesn't have parabolic ramp.

    Are there any major changes?

    Best regards…

    Due to the fractional N sigma delta engine that the ramp generation uses, this is quite difficult maybe even impossible.

  • RE: ADF4112 Fvco

    The only standalone PLLs we have that support FSK natively with dedicated trigger pins are the ADF4158/ADF4159/ADF4169, the HMC700 and the HMC703.

    I don't have any specific reference designs for implementing FSK with ADF4112 or any of our other standalone…
