All,

I've updated the block diagram of the Janus board based on the latest 
circuit and breadboard prototype tests.

< http://www.hamsdr.com/personaldirectory.aspx?id=255 >

The figures from testing the prototype using the AK5394A are

Noise Floor = -160dBm (in 11Hz FFT bandwidth)
Dynamic Range = 120dB
ENOB = 20

At 192kps the noise floor is totally flat.
