That's not really the question here and there are interfaces (internal
for example) for which it can go higher than that.

... again, no everything goes through those pins.

That's up to you really. I'm merely pointing out that out of the 3 clock
sources, 2 are setup to serve derivative of 44.1kHz, which is useless.
