The link in question isn't really I2S since it uses LVDS at the electrical layer. Such signals have no trouble travelling a moderate distance, and even basic HDMI cables are designed to handle much higher data rates. Whether these I2S/LVDS links have any advantage over USB or S/PDIF is another debate.I2S was never designed to 'travel' more than a few inches or leave the printed circuit board it was created on, hopping from one IC to another, so my answer would be "a very short cable."
Hi @mansr, fair enough, I agree with your comment, "Whether these I2S/LVDS links have any advantage over USB or S/PDIF is another debate." I did contemplate using I2S to link to my own TDA1541 DAC some years ago, with a view of avoiding the extra conversion stages, but lost interest. Perhaps when I have more time I will try to motivate myself to complete my project, unfortunately, several other, more interesting/worthwhile projects have attracted my attention.
What are you expecting to gain/improve by using I2S?
Most modern DACs at $500 and up already have a femtoclock.I2S has a dedicated clock, so very low jitter is easy to achieve
What are you expecting to gain/improve by using I2S?
You still have to convert to/from LVDS. It's a single chip at each end either way.All I could see was the ability to avoid conversion to SPDIF and back to interface my DIY TDA 1541 based I2S DAC.
Really, I wasn't expecting it to sound any better, much of my DIY stuff is just to have a play.
