View ArticleRe: AD-FMCOMMS5 with KC705
There are no problems. The AD9361 part of the no-OS is independent of any carrier or FPGA (it is all through the SPI). At present, we don't have a reference design on KC705. If you have successfully...

Yes-- by programming the corresponding registers. Go through the user doc. and try to understand the design and the user controls.
View ArticleRe: Using no OS driver with custom h/w in verilog
I suggest you try a simple (such as the "hello word") EDK tutorial using Vivado (IPI) and SDK first.After the basic concepts are clear, you can take on FMCOMMS1.

Re: Precision of the state-variable filters
Looks like I answered my own question. It's well known that fixed-point IIR filters have the most difficulty when set for a low frequency (f << fs), and high Q. Thus I made a test of 2nd...

Hi Jonathan, Thanks for the link to the document about the evaluation board. And sorry for the long time between my responses, but this is sort of a side project of mine, and I’ve been quite busy for...
View ArticleRe: AD9625 DDC Synchronization
Hi Aaron- The AD9625 outputs 16b of data when using the on-chip DDC modes. Therefore, control bit time-stamping cannot be used as N=16 and there is not spare digital bandwidth for control bits. I...

View ArticleRe: AD9625 DDC Synchronization
Ian, I did not realize that the SYSREF was used to reset the NCO on each ADC. Assuming I can synchronize my ADCs then I will be able to sync the NCOs using a one-shot mode. Thanks,Aaron
