That's funny ... my current design is squeezing ten pounds o' crap
into 2.125" by 5.125". 16 channels of ADC, plus ADC drivers, and a
Spartan XC3S200AN FPGA in 256-ball BGA. Now that the 3ANs are
available from Digikey, we're going to use them instead of the 3E. No
external config EPROM, which saves space, and I saved some more by
putting two Camera Link interfaces in the FPGA. Compared with the MSOP
opamps and ADCs, the FPGA's oscillator is huge.
