hi,
I know this is a question a litle bit exotic but I'm curious about it.
as you know the bottleneck of this board is the usb interface with about 26-24MB/s with the USB backend. This give us a max sample rate about 6 MSPS(2 bytes per sample and complex values).
the point is as the converters have 12 bits, 4 bits aren't used in data interface.
is we could use the extra 4 bits for sending part of next sample data we could increase the sample rate up to 8MSPS.
Even further, if we discard 4 bits of each sample and send just 8 bits (reducing SNR) per sample we could achieve 12MSPS.
what should be done in software and hardware to achieve this?.
thanks,
regards.
