TPA - USB Transport - Page 60

Yeah I am just saying to do it would require custom firmware. I am sure it is possible.

For everyone else out there DoP transmits DSD data over PCM.

Honestly - it sounds interresting, but its not a huge priority for me to start. But it could easily be added by the user since we will expose the JTAG interface.

If we find reasons to update the firmware people can apply such updates (or optional firmware) themselves.

that the TPA USB solution will also have single ended I2S output on U.FL for those of us who may want to place the board in close contact with a DAC board without the LVDS signaling.
I prefer to keep everything in one chassis for simplicity.

It will.

Russ! I will try and not bother you anymore, such that you can devote your "free" time to getting this board finalized.

Thanks. I am actually working on it right now (plus about 3 other boards to get made)

We have a couple of skunkworks projects Brian and I will announce when they are thoroughly tested.

If someone were cutting holes on a rear panel and wanted to have it ready to mount, would they go with type A or B USB?

B if you want to connect the DAC to a PC. A if it is a PC-like streamer, and you want to connect a drive to it.

You could do what I do and cut a standard Neutrik hole. Then you can fit any socket.

Thanks Leon.

10-4 on that!

I have multiple Neutrik's here and they will be on the back panel if/when chassis design is ever finished. I was planning on USB alongside the Teleporter above four S/PDIF inputs and letting OTTO II switch I2S inputs to the Sidecar to keep the I2S wiring short.

Take a look at those. The hole is larger than neutric but very solid and well isolated. Connection can be with molex type connector, not usb jack, PX0843/B Bulgin | Mouser
