Josh,
I'm glad that I answered on most of yours questions. If you need some more
information, don't hesitate to contact with me.

104MHz fifo bus in -> cross clock fifo to 26 MHz -> vita tx deframer ->

According to your idea. I think that this is fine, but are you're sure that
26MHz is enough for DSP calculations? In N2x0 DSP clock frequency was twice
higher than CPU clock.
