USB signal timing goes mainstream. Just an FYI


Now, to be fair, the issue here is rates that strain the "eye" and the ability to recognize the 1-0-1 transitions.  But in the analog domain the precision of those transitions affects Jitter and therefore half of the Cartesian plot that is PAM..  'later

This must qualify as the most obscure post in history: what exactly are you saying? I am not aware of any audio device employing USB4.

This isn’t audio relevant , it’s only computer related for computer hardware and networking geeks with USB-C connectors

The promoter companies having employees that participated in the USB4 Specification technical work group were: Apple Inc., Hewlett-Packard, Intel, Microsoft, Renesas Electronics, STMicroelectronics, and Texas Instruments.

USB4 by itself does not provide any generic data transfer mechanism or device classes like USB 3.x, but serves mostly as a way to tunnel other protocols like USB 3.2, DisplayPort, and optionally PCIe. While it does provide a native Host-to-Host protocol, as the name implies it is only available between two connected hosts; it is used to implement Host IP Networking.

missing the point. Don't worry about USB2 vs 3 vs 4 - its all just speed. As the speed rises timing becomes more critical.  Re-clockers have been a debated thing in audio over USB for some time. here's an example of the same approach being used for signal integrity mainstream. Nothing more, nothing less.

Just sayin', none of that technical gibberish ( and I'm a 30+ year EE in both fields) has the slightest thing to do with clock recovery and timing.  The fundamentals persist regardless of forma or content - the bits must be recovered, and in digital music protocols, the specific timing must be recovered to reconstruct fully half the Cartesian coordinate info needed for PAM or PAM like representations.

Over and out.
