Lightning Talk - Open hardware and software 400 MSPS USB Digitizer with COTS

on YouTube ↗04m

" summary

A low-cost digitizer implements 8-bit 400 MSPS conversion over USB 3.0 using cheap commercial evaluation boards, with external sampling & sync clocks to suit low-frequency radio-astronomy arrays. The prototype proves a functional pipeline but documents sustained transfer limits and potential missing-sample/indexing gaps unless an extra timestamping/index chip is added. Design files and code target an open learning project and are being prepared for availability for non-profit use.
