You know when someone is counting something really carefully, it's so tempting to start saying random numbers out loud ...?

I think we need someone to test one of these ....

USB Interfaces « Circuits@Home

If it's satisfactory for our purposes, we could contact the maker for a GB.

It doesn't work. PC couldn't recognize m2tech hiface when isolator was inserted. Ayre QB-9 worked - and it sounded better with isolator.

 

[Spartacus]

Thanks for the report. Did it work with some sample rates, or not at all?

 

[UnixMan]

Beacause the point of this USB to I2S is to get low jitter bit perfect I2S signal.
Isolation adds a lot of jitter, which is ok at the USB end since this solution works async. But if this jitter is added to the I2S, then it missed the whole point of the async system.

Indeed.

Question is: with this new board, wouldn't it be possible to work "backward" with the clock?

That is, you use a clean, low jitter local clock connected directly to your DAC and send it back (through isolation) to the m2tech?

If done this way, I think you could isolate I2S too without nasty consequences on jitter.

Am I overlooking something?

If not, we should ask for the new board design to allow for that too (it would require external clock inputs with provision to disable the internal one and at least some "control" output line to switch the external clock frequency).

BTW: of course, even in the above scenario, I guess that isolating USB too (if possible) would be a good (and possibly better) thing anyway.

 

[UnixMan]

It doesn't work. PC couldn't recognize m2tech hiface when isolator was inserted. Ayre QB-9 worked - and it sounded better with isolator.

Given that the new OEM board does not exists yet, I guess you've tried with the "hiFace" USB to S/PDIF "dongle".

Stupid question: that "dongle" is USB bus powered (normally from the host computer). Are you sure that you have provided a proper power supply on the USB bus after the isolator?

Dongle had it's own power.

[LeonvB]

If I'm not entering too late I'd like one too.

As for the USB side isolation: I think the ADuM4160 USB Isolator board is not going to work: "Supports full/low speed USB 2.0 compatible operation" as I understand it the M2tech needs hi speed (480Mbs) instead of full speed (12Mbps).

 

[ticknpop]

i'd like 2 of them
