NO! It's at the DAC - and ONLY at the DAC - that the jitter actually matters. That's where you want the nice, stable, low jitter oscillator.
Send the clock along a cable, or even a long PCB trace, and it starts to degrade. So, if you put the oscillator at the source and then connect it via a cable to the DAC, the DAC gets a degraded clock. That's when you start having to worry about PLLs and other de-jitter circuits, which gives you much the same sort of problem as SPDIF (though admittedly without the data-dependency to worry about). If you're going to use I2S but you put the clock at the transport end, you've really not achieved all the jitter reduction you could have done. Physically locate the crystal at the DAC end of the link, and the DAC gets the cleanest clock available anywhere in the system. -- AndyC_772 ------------------------------------------------------------------------ AndyC_772's Profile: http://forums.slimdevices.com/member.php?userid=10472 View this thread: http://forums.slimdevices.com/showthread.php?t=35642 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
