Overview
We are designing an FPGA Mezzanine card (standard FMC/Vita 57) for high-channel-count electrophysiology, with 128 channels (potentially up to 512), based upon Intan Tech's RHA2132 (2 uV rms input-referred noise), sampled at 25kHz 18bit by AD7982. We are basing our design on the reference design provided by Reid Harrison of Intan Tech for their 16-channel evaluation board.
In order to have an integrated solution we intend to have as default carrier the Opal Kelly Shuttle LX1, an inexpensive USB FMC carrier with an excellent USB controller. The integrated solution will be completed with software on the PC side to grab to disk continuously and/or display in some fashion all 128 channels.
