Again, the fact that the input sequence is not perfectly timed is not relevant providing the data recovery circuitry/algorithms are able to cope with the imperfections. The use of data corrections (CRCs etc) can ensure bit perfect output sequence results. The use of quality retiming can ensure extremely low jitter prior to the conversion (or indeed during the conversion) to analog.
For high rate data recovery PLLs with jitter in the 100fs region or lower are de rigeur. For audio the best PLLs/DLLs used are sub ps. The theory concerning the eventual SINAD of the data at the output and the resulting impairments is quite clear. There's a reason that digital recording/playback of audio has improved by so much in the last three decades.
