Guess you overlooked the fact that our EtherREGEN also includes an SFP for optical transceivers. So your (apparently delete) post about us not offering optical is quite incorrect.
And Audiobomber is correct: John Swenson was a senior chip engineer for LSI Logic>Avago>Broadcom for 31 years, with his specialty being design of the power networks inside large and small ASICs. He has literally designed (as part of a large team of course) Ethernet switch chips and PHYs—used in Cisco and other enterprise-level equipment.
Our ‘white paper’ was our attempt to explain in lay terms some of the key underlying factors about why people are able to hear the differences they do with network (and USB) gear in music systems. It is not about the bits—it about ground-plane perturbations which propagate, from everything upstream and from within the chips themselves!
Remember: A clock is just a highly accurate periodic voltage (either square or sine wave) with risetime/ramp which other chips use to trigger off of at some set voltage along that ramp. But a clock’s voltage is referenced to a zero-volt ground plane. If that ground plane bounces—even a tiny bit—it moves the ramp of the clock forward in time. THAT’S JITTER!
So you can call our little paper ”Marketing” all you want. But please show me any other company in this space who is even attempting to educate the consumer about the real mechanisms taking place and why it matters.
I see an awful lot of expensive switches out with either no original innovation and/or a lack of willingness to even publish a clear photo of their board with an explanation about their design. (And a good number of these switches are simply mass-market PCBs with some clocking mods and a power supply tacked on and put into a fancy case.)
