And to add the the confusion, most of these clocks are "word-clocks", not bit-clocks or master-clocks. Recently I discovered (while designing mods and a new DAC), that in most modern DAC chips, the bit-clock or even sometimes the master-clock is actually used for the final A/D clocking, not the word-clock. This is why it is defined more like a control-signal, not a clock in the timing of the datasheets.After discovering this, I understand why I2S interfaces sound so good and what clock to optimize for each type of DAC chip. Makes a tremendous difference. It would not surprise me at all to see an external word-clock on a DAC that actually uses the bit-clock for the D/A conversion. I've seen crazier stuff in this business....
The KISS principal still works...even with Digital.
