Originally posted by Wombat I have a DAC here around that claims tobe jitter-free.They "resample" the whole incoming signal to a new stream.Can somebody explain?A view in the service manual shows that the incoming signal is send to a to a dsp -> sdram -> sample rate converter -> d/a part with the clock crosslinked to incoming clock with a sampling rate counter and flame counter.

Originally posted by crazyboy_T If you put the clock source on the external DAC you could eliminate jitter (almost) completely without any buffering. There are several disadvantages, though:- needs a sound card that can sync to an external clock source on its spdif input- DAC needs to have an spdif output to transmit the clock- must change clock/divider manually on DAC for multiple sample rate support
I think that the case of AD1890 and AD1891 SamplePorts is not what can be found at consumer audio
