• About the FSK of ADF4159

    Hello,

    About the ADF4159,

    I have pasted P15 Figure 15 in the ADF4159 data sheet below.

    Is there any way to control the frequency increment (in red) individually?

    Regards,

  • Lock detect of ADF4159

    Hi

    I saw "AN-873" Application Note about structure of Lock Detect in PLL IC's ,I need this information about ADF4159. Is there similar Application Note for ADF4159 or Does this Application Note also applies to ADF4159?

    Thanks.

  • in the ADF4159+ADF5901,who decide the VCO’s frequency ?

    We use ADF4159 and ADF5901 to produce RF signal.In ADF4159 datasheet,we can set register to set vco’s frequency,and In ADF5901 datasheet,we can set register to set vco’s frequency.the question is:if in the ADF4159+ADF5901,we set different VCO’s frequency…

    Hello can i know how to programe the ADF4159 using SPI thanks.

  • RE: some questions about ADF5901 and ADF4159

    So if i use ADF4159 with ADF5901. the R-DIVIDER and N-DIVIDER in ADF4159 and ADF5901 should be set the same.

  • what is the meaning of DIGITAL LOCK DETECT in the R0 of adf4159?

    we set MUXOUT is DIGITAL LOCK DETECT in R0.if adf4159 is not lock,the MUXOUT is 0?similarly,if adf4159 is locked,the MUXOUT is 1?

    What is the supported reference crystal input waveform for ADF4159??

    Is there any recommended 100MHz crystal type?

  • ADF4159

    Can the ADF4159 be used to generate sweep triangles from 7.7 GHz to 8.8 GHz?

  • adf4159

    The data sheet for the ADF4159 specifies AIdd, DIdd, and Ip power supply currents for Fpdf = 110 MHz.

    Do these scale with the Fpfd value? Is data available for the device current usage vs. Fpfd?

    Thank you.
