Umm, not really.  You might need a one-shot for the 50ns glich, but other 
than that, it's clocked.

Or, maybe I'm missing some point.  I was very deep into I2C a few years 
ago, so I do know the protocol fairly well, but I don't know the hpsdr 
architecture all that well yet.

It's not what I know that counts. 
It's what I can remember in time to use.
