Introducing DIY fiber optical i2s send/receive boards

[TNT]

:-D

Well, i guess we just hav to wait a week or two for more info and reports on your prototypes.

So of used the i2s version, could I only use the CLK to transfer only a clock on the opto?
//

Can you be more specific about the clock you want to transmit? How many ohms?

Why not a name that indicates it's function?

He can call it the Automobile Cheese Tyrant, for all it matters...

Do you know what an AHB3 is? It's an amplifier, but would you know if you weren't already familiar with it?

Lets try to stay on topic...

Do you mean the output impedance of the clock board? We are assuming 3,3v right?

I will probably try to send one fo these: The Well Tempered Master Clock - Building a low phase noise/jitter crystal oscillator

They seem to be 33 ohm. But possible to make 50 or 75 as well by changing some resistors re:

Yes. Right now there is a 50 ohm resistor to ground.

I want I2s transmission. Thread title says it all.

It going to depend on what you are doing. The boards have standard 3.3V CMOS digital ins and outs. If this is what you are doing, then you can use it as is.

On your board?

Yup Getting I2S out of a mini DSP to DACs by/in the speakers. Irrational desire to galvanically isolate because I can!

 

[TNT]

Greater irrationality has been seen than that 🙂

...All I can say is that it's in progress...

Talking about progress, how are things coming along?
