- cedivad 4y agoA few reasons: (1) The AFE7903 wouldn't allow for any modularity in the system (look at what we are calling the RFNM interface on the website, I think that's the real reason this platform will work), (2) Pricing, that single chip would cost in quantity 1k more than our current BOM, and you still need to add FPGAs, frontend, etc. next to it. (3) Those single chip frontend modules don't have the embedded DSP cores we can use to do things like processing FFTs in real time and feeding them to a browser with no computing on the host, which I think will be very cool (multiple 160 MHz FFTs with a gr-phosphor like visualisation I think has never been done before at this price point).
