Unfortunately, this looks like an example of a wiki that is wrong and needs editing.... The SPDIF and AES/EBU interfaces have -always- encoded the clock into the bit stream. It's also wrong in the underlying premise. Jitter is always present, both in independent clock transmissions, and in encoded transmissions. The reason an independent clock is preferred, is that it removes sensitivities to data patterns in the clock recovery circuit. In other words, it's possible for your favorite music to increase or decrease jitter in an encoded clock transmission! -- DCtoDaylight Audiophile wish list: Zero Distortion, Infinite Signal to Noise Ratio, and a Bandwidth from DC to Daylight ------------------------------------------------------------------------ DCtoDaylight's Profile: http://forums.slimdevices.com/member.php?userid=7284 View this thread: http://forums.slimdevices.com/showthread.php?t=52817 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
