Unless a digital system is using a master/slave clock architecture, it needs to use a PLL to synchronize the transport signal to the DAC. A PLL can reduce jitter in the incoming signal, but has some of its own inherent jitter if the clock in the transport has any difference from the receiving clock. A FIFO buffer can help reduce jitter in this kind of design, but it cannot eliminate it. Do a Yahoo/Google search on "asynchronous jitter" and see what comes up...this topic has been researched at length by the telecom industry, military, and yes, the audio industry. Pretty much all the credible research says that re-clocking does not "eliminate jitter", and in some cases it says that the act of re-clocking can sometimes ADD jitter. Here's an interesting one from said Yahoo search: http://users.verat.net/~rogic2/1541/pdf/ASR_Measurements.pdf#search='asynchronous%20jitter' -- PhilNYC Sonic Spirits Inc. http://www.sonicspirits.com ------------------------------------------------------------------------ PhilNYC's Profile: http://forums.slimdevices.com/member.php?userid=837 View this thread: http://forums.slimdevices.com/showthread.php?t=29450 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
