Morbius is correct, if the master clock is local to the DAC chip itself, then the jitter will be minimized. This is not necessarily the case with external "bit clocks" that a few DAC's and CD players utilize. This is often more difficult than it seems at first blush. The master clock must generate several clocks or at least a very high-frequency clock from DAC to transport. Some of the transport chips may use the higher frequency clock, such as 16.9344 MHz. The analogy to the disk-based system doesn't hold water though, IMO. |
