Default Why AC coupled XO?

I see most of you guys use ac coupled output on your XO, is this only to remove dc offsets between XO and receiver or are there other reasons?

I assume it would be difficult getting a nice square wave through a cap!

Some people may use the coupling cap as a free pole.

Yes it is!!..But much more difficult is getting a nice square wave reproduced by a loudspeaker

We are talking digital electronics here and in digital electronics a square wave is important. The question is if a XO ( digital clock module ) should be coupled capacitively or not.

XO's are precision low jitter clock modules for use in cd-players etc.
