Humm, a neat all in one solution.

Two things to consider if it does not work in your application.
1) Does the 1.8V supply rise before the +3.3V or is it in parallel with +3.3V?
2) The clock source, rise/fall times should be <2ns, if it is slower, add a schmitt buffer + series terminator.

You'll want edge coupled microstrip as a minimum for the SATA, the edge rates are crazy.
