Let me preface this by saying I am very new to FPGA's.
I am trying to find a way to sample 3 channels simultaneously at a resolution of 16 bits per channel and at a rate of at least 600KSPS per channel and then 2 channels at a resolution of 16 bits at a rate of at least 200KSPS. I've decided on using an FPGA and am now looking at what will convert the analog signal into digital signals.
My largest problem is that I do not have the time to create a custom pcb that contains the discrete ADCs and the FPGA on one board. So I have been searching high an low for an FPGA dev board that contains adcs that meet my specs. Since I've been unable to locate such a dev board I'm thinking about the possibility of locating an external board that contains the adcs I need and then interfacing that to a standard fpga dev board. I still haven't had much luck in this area either, but then again I really don't know what I'm looking for in terms of names/terminology.
I have located some HSMC boards that have analog front ends, but I don't think I want to use an analog front end because I am already amplifying the signal and then low pass filtering it. I really would like to find a mezzanine card that just has analog to digital converters on them.
Any help would be greatly appreciated.
