I can see one advantage to using an external, GPS-referenced external word clock: it would allow multiple units listening to the same Internet audio broadcast at diverse locations to stay exactly in sync without dropping or duplicating samples, assuming the sender was also using a GPS-referenced clock. Any extremely high accuracy clock source would probably allow precise synchronization over reasonably long intervals, even if not locked to a common source such as GPS.
XM radio uses GPS to generate a house clock signal so the remote studios, New York, Nashville, Toronto, etc, are locked in sync with Washington. Interestingly enough, this master clock DOES NOT get carried through to the DAC in XM receivers. I once took two XM receivers, tuned to the same channel, and viewed the WCLK signals on a dual trace scope. They tended to hunt back-and-forth relative to each other, obviously steered by the master clock from Washington, but not tightly locked to it. -- Timothy Stockman ------------------------------------------------------------------------ Timothy Stockman's Profile: http://forums.slimdevices.com/member.php?userid=8867 View this thread: http://forums.slimdevices.com/showthread.php?t=35570 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
