Hi All,
We want to use ADF4355-2 to generate LO for Demodulator and modulator at the same time.
System RF output frequency maybe will at 3GHz to 4GHz.
We have some question as below need your help!
I am looking at using a DDS to provide the reference to a PLL. The PLL (ADF4355) will act as a simple multiplier for the DDS output. I want to use the internal VCOs of the ADF4355 and its output dividers. What I want to know is how does the ADF4355 select…
Hello,
Our customer is using ADF4355 and ADF5355 by same circuit and layout. But, the output level of ADF4355 is lower than ADF5355. The output level is around -5dBm at 3400MHz and -30dBm at 6000MHz. The register setting of ADF4355 is also same as ADF5355…
Hi,
I have a working design with the ADF4355, and on the followup spin on my board I switched to the ADF4356 thinking it had slightly better performance and was a simple drop in replacement. Now I am having trouble getting the PLL to lock. I have done…
Can you use 2 parts? 2 ADF4351 evaluation boards would do what you're trying to do. If you want much narrower than 10 kHz spacing, try the 2 ADF4355-2 boards.
There are no difference between the boards.
I still believe that the problem is between the SPD board and ADF4355. I think the communication between both has been cut off. Is there a way to prove this? Is there a way to check if the ADF4355 is still…
The maximum modulus on the ADF4351 is 4095. For a reference frequency of 10 MHz, this gives a resolution of 2.44 kHz.
The ADF4355-2 has a much higher modulus. With a reference frequency of 10 MHz, you can achieve 0.1 Hz resolution. For more information…
Dear ADI team,
last week I order samples of ADF4355BCPZ, but now when i have receive them i see that on chip is written: ADF4355-2 (but on pack list and box is written: ADF4355BCPZ).
This is strange as ADF4355 is for max output frequency 6.8GHz and…
