Digital transfer: USB - SPDIF - I2S - LAN - Wifi... Oh man! Too difficult!
I just cut this little extract out of the USB cables expensive v cheap thread. As my question is different, broader and - well yes - more interesting than the USB-price-per-metre-conundrum , I thought I should start a new thread on it.
The actual timing of the 1s and 0s doesn't matter either because the receiving device can store the incoming signal in a buffer and take it out at the correct rate. This is why CD players in cars don't suffer from the movement of the car.
Does your DAC do this? Very few do.
Most rely on slaving their clock to the input bitstream.
Yep I know. I just mentioned the possibility because it is there.
Now that is a topic I'm struggling with: clocking and reclocking of digital signals. As far as I understand it (toddler grade - I apologize), a DAC with async USB just pulls the data in and clocks the signal itself; an I2S cable [or I2S connection in a CDP] transfers the raw data ànd the clock signal separately; while a SPDIF (coax or optical) just beats data and clocking together and transfers it as one signal; and that's where jitter kicks in, right? Or do some DACs also reclock the SPDIF signal (and if so: examples?)? And how about network players? As I said before: Oh man! Too difficult!
