[sdiy] Using dual BBD chips for higher clock frequency

BBD is only about 12 bits accuracy at best, and there's plenty of cheap ADC/DACs that can run 12 bits at many megahertz.    Pair one of these with a cheap ARM processor with lots of memory.

Isn't one of the advantages of using a BBD over a digital solution is the clocking can go to 500 KHz to 1MHz?

So depending on the clock freq you can get the aliasing filters higher up and have better freq range.
