Hi,
Now, In my design, there are 16 ADCs and an FPGA, the FPGA controls the ADCs and receives the data from these ADCs.
Besides the FPGA, there are other digital circuits(DSP, SDRAM), in other words, the digital section is very noisy.
Also, there RF amplifier and RF switch on the analog section.
I plan to isolate the ADCs from Digital sections. I have two options,
(1) opto-couplers from Avago, ACSL-6210/6400.
(1) RF isolaters from Silicon Lab, Si8460.
I am very hard to make a decide now, which one is better?
Thank you very much.
