The ADC circuit is shown at page 39 and 40 of Stratix II DSP Board schematics. Clock AC coupling is not an issue, cause cutoff frequency is much lower than specified minimum sampling frequency, but analog in AC coupling is.
Transformer coupling is an effective way to produce a differential signal with good common mode rejection, if DC and low frequency components aren't of interest. To transmit DC signals, a differential amplifier would be used instead.

Ok let me look it up, I will come back and bug you after i read it
thank thank you so much
Happy easter :)
