Because the input and output clocks are nominally (but not exactly) the same as each other, you can't just buffer the data and have it take care of itself.
Have a go at designing and building yourself a DAC, and you will start to appreciate the issues involved. It's really not quite as straightforward as you seem to think it is! -- Patrick Dixon www.at-tunes.co.uk ------------------------------------------------------------------------ Patrick Dixon's Profile: http://forums.slimdevices.com/member.php?userid=90 View this thread: http://forums.slimdevices.com/showthread.php?t=34292 _______________________________________________ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/discuss
