Thank you, James, for your reply. I have tried ROACH2v2, and the programmer
working with me had some issues porting their ROACH1 design to ROACH2.
However, it looks like ROACH2 would be the way to go, and that the
ADC16x250-8 is usable only with ROACH2 currently.
In this context, may I ask if
Dear CASPERites,
I am trying to design a cheap 16-element interferometer using a ROACH1
board with 250-500 MHz bandwidth. Would you suggest the ADC16x250-8 for
this purpose?
Best regards,
Siddharth

Dear Siddharth
Yes, we have two 16-input boards (total 32 inputs) working correctly on
ROACH-2. We use it to get 16 simultaneous complex RF beams. You are welcome to
follow up if you want more details. My PhD student Viduneth on CC is
experienced in it.
Cheers,

If you've got a ROACH2, there's not much point in getting started on a
ROACH1, the tools are more mature on a ROACH2.
I can't provide much support myself, but there are other users in the
mailing list who might be able to get you started.

Siddharth,
ROACH1 is quite deprecated now, we don't recommend it for new projects.
There are still a number of them floating around, but no active development
on the libraries to support them.
I don't know of any ADCs with more than 2 inputs. You'd also be quite
pressed to fit a full 16-element
Dear CASPERites,
Many, thanks, Indrajit, for your reply. Are there ADCs that can be used
with ROACH1 and have more than 2 inputs? I am starting from scratch, and as
far as I can see from CASPER websites, it would be easier to set up ROACH1
as compared to ROACH2, and given the large number of
Dear siddharth,
Please go through this message. ADC16 is not (yet?) supported on ROACH1. So consider with ROACH 2.
