• ADF5356 supply input

    Hi,

    In ADF5356 datasheet applications information, a single voltage regulator has been considered for 3.3V  and 5V supply input. Whereas, in evaluation board schematic two no's of 3.3V regulators have been used (One regulator for AVDD and DVDD lines and…

  • ADF5356 IIO support

    Hi, I am considering purchasing the EVAL-ADF5356, but I understand that the AD provided control software is Windows only. Does this eval board have IIO support, so that I could put together a script to control the eval board in Linux? If support for this…

  • EVAL-ADF5356 max frequency

    Hi, I just wanted to confirm before purchasing, but is it true that the EVAL-ADF5356 by default can only output at max 6.8 GHz? I understand the chip can support an external VCO that goes up to 13.6 GHz, but reading the datasheet it looks to me like the…

  • ADF5356 output frequency response

    Hello.

    We made wideband RF genegator using ADF5356. our PCB have same schematic diagram as evaluation board. But we have a problem. Frequency response of our device at rf output of ADF5356 is very non-linear. It's broken line and it's mush less uniformly…

  • ADF5356 fast lock

    Hi

    I'm using the ADF5356 demoboard and I am loocking for the implemantation and test of the fast lock procedure describe on the aplication note AN-1353.

    It's said that a custom control software is available on request .

    Where can I have access…

  • ADF5356 Frequency Sweep

    I want to sweep from 10 GHz to 10.5 GHz. I looked at the evaluation board software and it appears to rewrite the registers for each of the individual frequencies within a sweep. Is there a way to set a sweep mode, like in the ADF4159, so that you don…

  • Messy PLL with ADF5356

    I've been trying to design a pll with the ADF5356. We are getting a really messy output. The center frequency is solid but as you can see that there is no clear peak. Do you have any idea of what can cause this type of output?  Thanks.

  • Phase Noise Optimization ADF5356

    Hello,

    I am using the ADF5356 in an application where I need to be able to tune the DDS in 438mHz (yes, milli)  steps for around +/- 500 channels centered around 9.375 GHz. I've read the datasheet front to back but it is still not clear to me how to optimize…

  • ADF5356 loop bandwidth problem

    We use the ADF5356 for generating fixed oscillators with lowest possible phase noise.

    We use 100M PFD frequency, and use the sequence where the setting with halved PFD is written first with autocal enabled, followed by a R13,4,2,1,0 (autocal diabled)…

  • ADF5356 Digital Lock Not Working

    Hello,

    I've made a board based on the recommended design but with a different ref clock and a single ended configuration. The loop filter remained as in the datasheet. Unfortunately, the MUXOUT pin never goes high (I've configured it for digital lock…
