In that diagram, it looks like the CPU-side simply doesn't receive a system clock at all, so it's recovering any clock by multiplying up the bit clock.
Practically speaking this is the case for most simple CPU DAIs, unless you're doing DSP or generating the clocks you just need a clock that is strictly faster than the data rate, synchronisation is irrelevant.
