Review: Analog Devices ADF4351

Posted on Monday, December 10th, 2012 in Chips, RF by the machinegeek

Sebastian has been tinkering with the Analog Devices ADF4351 eval board and written a review. “The ADF4351 from Analog Devices (ADI) is a modern wideband PLL synthesizer with integrated low phase noise VCO. It is capable of generating signals between 35 MHz to 4400 MHz with a very low jitter of typical 0.3 ps. ADI agreed to send me the EVAL-ADF4351EB1Z, an evaluation board for the ADF4351, for review purposes.” Being an amateur radio operator (KF5OBS), Sebastian is already thinking about possible applications for this chip as a modern alternative to synthesizer chips used in some earlier radio designs. His complete review can be found on Sebastian’s Jaunty Electronics website.

According to the ADI website this eval board lists for $175, though Sebastian reports that the chip itself goes for $8.25 each (when purchased in bulk.)

    “After trying this board out for a while, I highly recommend this chip.” The web page has some nice photos of the board, but were any actual tests done on the signal output? If it is a review, I expected to see some comment on how well the board works, if not actual numbers. FYI, the single-unit price from DigiKey on this chip is just over 14 dollars.

      I agree. But usually, if I stuff that into a review, people don’t read it because its ‘too long’. What counts for videos counts even more for text. I therefore usually take the review posts as ‘tease’ for the articles that will come in the future. Future articles will show practical examples with example waveforms, spectrum, etc.

    I am working with ADF4351 for a while. Using a micro controller to program it, written a program to calculate INT, FRAC , MOD etc for a given particular frequency. In one particular case i need to program it on its full freq range 35MHz to 4400MHz. Its working fine on upper freq range but its not working for freq less than 127MHz. If i set it for any thing less than 127MHz it does not work, output does not change for below 127MHz. Im not using ADF4351 eval board from Analog Devices but a custom board with ADF4351 on it.

    What a useless post… what part of this is a review ?
