User manual says pll2x8, pll2x4, pll2x2, pll2 for all the the clocks.
So the order here should be reversed. Same for the others.

Newline. And the manuals don't have anything on the SPDIF clock,
so I can't comment on it.

Apart from the title and the clock orders, everything looks good.
Jon should test this with the above corrected.
