I read a calculation about determining the bandwidth of USB https://www.edn.com/electronics-blogs/all-aboard-/4425691/Rule-of-Thumb--2--Signal-bandwidth-from-clock-frequency
Roughly what was said is:
USB 2.0 = 480 Mbps Thus the clock = 240 MHz Multiply by 5 to get Bandwidth and get ~ 1GHz
So trying this for USB 3.0 I think I'd end up with this:
USB3.0 = 640MBps clock = 2560 Mhz Bandwidth = ~12Ghz
As far as I know however, USB 3 noise runs somewhere in the 2.5Ghz range. Is the formula given in the article incorrect? Or is there a different way I should be going about calculating the frequency of different signals?
