We are using AD9681 with HSC-ADC-EVALDZ.
Is it possible to measure phase difference between all 8 analog inputs and how to do it?
Maybe, you have FPGA code enabled us to get samples all 8 analog inputs simultaneously for this purpose?
I apologize for the slow reply.
The AD9681 samples simultaneously across all 8 channels, but unfortunately the FPGA does not capture data in a time aligned fashion, so you will not be able to measure phase difference between all 8 channels using the existing FPGA program.
I'm sorry this does not meet your needs.
