• ADF4169 MUXout abnormal

    I have two adf4169 boards, which use SPI (3.3V) of MCU  convert to 1.8V logic to control their registers. The performance of the two boards are different.

    Board 1:  VCO output can be locked  by adjusting the current value of loop filter and Icp…

  • Phase consistency between two ADF4159/ADF4169 PLLs

    Is it possible to achieve phase consistency between two
    ADF4159/ADF4169 PLLs ?

    Two ADF4156 PLLs can be programmed to achieve phase consistency, in the datasheet this is explained in the PHASE RESYNC section. Unfortunately the ADF4156 does not have any…

  • ADF4169

    With a reference frequency of 112 MHz what level of fractional boundary spurious can I expect to see over the 4 to 8 GHz range?  With 112 MHz reference frequency the step size is approximately 3.338 Hz.

  • ADF4169 - poor Phase Noise performance or no LD signal

    Hello,

    I'm trying to build PLL synthesizer based on ADF4169 PLL and HMC735 VCO. It's assumed to cover a bandwidth of 1 GHz with center frequency at 11.18 GHz. I've designed the loop filter for this application with LBW 100 kHz using ADIsimPLL. The reference…

  • ADF4169 Output signal

    Hi,

    In datasheet, it is mentioned that, this IC can be used for FSK function.

    Can we give external pulse signal to this IC?

    Can anyone clarify whether ADF4169 can be used for PWM or not? If not, request to suggest a part which can support PWM.

  • ADF4169: Sawtooth Ramp in synchronization with the external trigger

    Hi,

    Is the following operation possible using the ADF4169?

         [1] The lamp starts in synchronization with the external trigger input. There is zero (or few ns) delay from rising edge of trigger to the lamp start.

         [2] Ramp up with 160us. Frequency linearly…

  • ADF4169 Fast Ramp Mode control w/ TXdata pin or external trigger ?

    Hi all,


    Our customer will plan to design the FMCW radar w/ ADF4169.


    Using the function "Delay Between Ramps" and "Fast Ramp Mode" of ADF4169,

    can we control like the "Digital Ramp Generator (DRG) of DDS" ?

    It is only used…
