I don't know if this makes things easier or not, but the act of sampling itself is like a mixer. If you sample one clock with the other, it would produce a beat frequency. Sampling here just means a strobing a D flip flop. The output will be low frequency, so the error could be measured with a uP.

This is just a variant on the decimation demodulators that were used before DSPs were powerful.
