Infamous? Are you sure?

Infamous = known for bad quality....Did you you mean 'renown' or or 'well-known'?

I mean infamous for "to wait for the shipment forever".  Probably well-known is a better wording but this word sounds too positive to me.

And the only way to cross that moat is still to use the only one 100mhz RJ45 port ?

 

Then if one are an opticalRendu user, use that 5th RJ45 as input and the SFP as output.

 

Should have exactly same effect as going the other way (fiber in), or use one of the 4 other RJ45 as input.

 

All three of your statements are correct! :D (Though 100Mbps not 100MHz)

"the M12 SWITCH GOLD conveys the full density of sound and a subtle feeling of the air. Its high-frequency range is transparent, and the mid and bass areas are clear with high S/N." 

 

Makes perfect sense. You always want to convey the full density of sound. The thicker the snake oil, the more delicious. Now, that's infamous!

Any ASer bought the M12?  it's been around for years but I find it too expensive.  This may not be the thread to discuss the M12.  Any guy will point a thread of M12 in AS for a poor soul?

Just for fun, here is a purposely fuzzy reduction of the EtherREGEN block diagram I was updating today (working on revised list of the 10 required LT3042/45 voltage regulators).  Thought I would tease you guys.  x-D

 

When we are closer to ready and have time I'll publish a readable version so you can see the data flow and clocking domains, etc.  This one has all the part numbers so I need to make it fuzzy.  Plus it is not made pretty or fancy, it's just for our internal discussions and mark-up.

 

The only hint I'll give is that the pale horizontal line near the middle of the diagram that cuts across everything is the "moat."  Anything that sits on it are data, clock, or power isolators.

Is it possible for John S. to design a USB optical isolator using this technology?

Optical ethernet in and usb out or what are you actually requesting ?

USB in > optical isolation > USB out. Using USB in to power the first optical stage and external power for the second optical stage and USB out. Let's call it IsoptoRegen.

Alex, Ayre has implemented optical isolation to their QB-9 DSD USB input, I suppose it could be implemented in an external device as well ("OpticalRegen")?

 

"The QB-9DSD also utilizes opto-couplers to provide
total electrical isolation for the connections between
your computer and music system. This minimizes
the introduction of unwanted radio-frequency
interference (RFI), generated by all computers."

Hi:

As explained many times in the past, DACs (or DDCs) with digital isolators (be they optical, RF, capacitive, GMR, etc.) must ALWAYS position them AFTER the USB input stage--on the I2S lines into the rest of the DAC.  [Please reread "a)" in my above post to understand why.]

The sole exceptions are the couple of DAC makers who are using the (now discontinued) Silanna ICE08USB chip right at the USB input--before the XMOS or other USB processor (those are the $6K Auralic Vega G2, and the @PeterSt's NOS1a G3).

 

The ISO REGEN already provides galvanic isolation--though we admit that whole Silanna>USB3.1 hub scheme is not always flawless in use (iFi with their similar iGalvanic suffers with the same connectivity support issues that we do; that's why we both have isolation defeat swtiches on our devices).  By nature the ground-dependent USB signal does not lend itself to these tricks.  

But we have ideas for the future.

 

While I know that conceptually "optical" isolation has an appeal--I mean what's more galvanically isolated than light?  But realize that there must be transceivers on both sides, the data goes in only once direction through each bit of isolation channel, and that clocking also has to move across the isolation moat.  Plus opto-isolators are not the lowest jitter for their function, so as with using any digital isolator, using a really low jitter, high-speed flip-flop afterward is mandatory for good performance.

 

Okay, no more USB isolation talk in the EtherREGEN thread! :D

The latter does both. :P

 

Which reminds me of something ... :rolleyes:

Funny, even the original Uptone Audio REGEN made a significant improvement to the sound of my QB-9 DSD.

I thought I read somewhere in this thread that the etherREGEN would be launched in the first quarter of this year. No signs of this yet. Alex (@Superdad), can you give some insights, planning wise?

He did. And it’s Q2 now. (But you have to figure it out from the text below).
