TPA - USB Transport

Hi Russ/Brian,

Just a few quick questions, if I may.

What are the expected dimensions of the module?

What power supply requirements will it have?

Will it utilise the new faster optocouplers allowing 24/192 with galvanic isolation?

Cheers,
Phil

Hey Russ, just wondering how you going with XMOS module?

I am implementing an XMOS based solution. Stay tuned.

I am guessing first prototypes are 6-8 weeks off. Just depends on other time demands.

Cheers!

Funny you should ask. very well actually.

Yesterday I was hacking up a prototype based on some stuff XMOS sent me to play with. I am able to get it working, but It still needs some attention.

I am going to be focusing on that module very hard over the next few weeks.

Cheers!

You writing your own drivers? I looked at that while ago with the XMOS, but figured it would swallow a big chunk of my life, so bought a Hiface instead!

No, not writing my own. Using the stock drivers on my macbook pro right now.

I have also used the driver XMOS provides for windows. Both work just fine.

To get higher than 192khz via USB audio I will likely need to do some customization of the driver.

For now I have played signals up to 384khz directly from USB storage. But, I have not perfected this yet.

My hope is to be able to make the board work both as a host controller with USB storage and as a USB audio device. We shall see...

I guess the USB/SPDIF(I2S?) board might be even a bigger success than the Buffalo II, so you'd better be prepared for that, I hope I won't need to stay awake all night again.

Please Russ, show it the kids...

Who said anything about S/PDIF? I thought the module was for the Buffalo DAC.
