Introducing the bit "Teleporter"

[karvid]

Test rig is done, and I have started building them. I should be able to get a few for sale in the next couple days.

Any idea of the price yet?

 

[BrianDonegan]

Price is not final, but it's looking like $40 each.

 

[luvdunhill]

Would it be possible to get a panel mounting diagram, as well? The two holes and the square hole dimensions should suffice.

 

[BrianDonegan]

Cutout dimensions are 16.51 ± .25mm (.650 ± .010 in) across, and 13.95 ± 0.25mm (.535 ± .010in) vertically.

PDF for ethernet jack attached.

I will get a DXF file of the mounting pattern posted soon.

Is it possible to use just one module to achieve galvanic isolation for I2S ?

I2S input => teleporter => I2S output => Buffalo III DAC

No.

You would need TTL I2S input => teleporter(transmitter) => DIFFERENTIAL I2S => teleporter(receiver) => TTL I2S output => Buffalo III DAC

 

[BrianDonegan]

There would be no ground reference at the Buffalo end to use just one half of the differential signal. You could supply that from the source, but then, well, no isolation.

 

[Russ White]

That and the LVDS signal level would be far too small.

Sorry, I do not quite understand all the technical details. For dummies:

If I just want to have galvanic isolation, I'd use IL715 chips as described here:
Which Digital Isolators for I2S? …or NOT H i F i D U I N O

If I want to have galvanic isolation plus the benefit of transmiitting the signal over longer wires, I'd use two of your Teleporter modules.

Question:
To have also galvanic isolation with two of your modules, would I need to cut/break the shielding (gnd) of the ethernet cable between the transmitting and receiving module ?

 

[BrianDonegan]

There is no ground in the ethernet connection, just four differential pairs.

Here is a Front Panel Express file containing the Teleporter part. Right click and create a user macro in your library.

Also, a DXF of the part.

Thanks! Please post once they hit the website!

How many Teleporters would be needed for 8 channels? I am thinking of picking up 8 channels of i2s from the computer using the Xonar ST.

Thanks, Mike

Nice if you will be willing to share the I2S pick up points in the Xonar ST board...

Ok, I read the post in your link. There are 7 pins that have the data we need. Your bit teleporter has 4 channels. So I would need 2 transmitter boards and 2 receiver boards. Is that correct?

Well, 6-pins (you don't need the Vdd), but yes, two transmitters/receivers for that.

Please give me information on where to order Teleporter.

Another use for the Teleporter will be to connect to a digital crossover or equaliser.

I use a couple of DEQX units connected to the XONAR card configured as quadrophonic and then feed their digital output into Buffalo DACs that, in turn, feed each individual speaker driver (the DEQX allows discrete calibration of each individual driver as well as being a crossover and room eq).

Tapping into the I2S made an astounding difference. The Buffalo DAC in concert with the digital processing capabilities of the DEQX is simply astounding. Unfortunately, running I2S any real distance is extremely problematic - particularly at higher bitrates. Hopefully, the Teleporter is the answer to my prayers
