Asynchronous I2S FIFO project, an ultimate weapon to fight the jitter

[MisterRogers]

Ditto on trying one out Ian - Just say the word.

Nice! I would also be interested in trying one out so +1 for group buy.

Another digital isolator for you would be the ADuM1400/1401 or 1402. You can find these here: Optocoupler Alternative | Analog Devices

Let me know what you think.

hmmmm anyone got an IP on the above?

i'm going to assume you work at ADI, this is a non-commercial area

BTW is there an ETA for the Si570 clock board?

Cheers,

Thanks guys for offering the try out. Will reserve one of the prototype PCB for each of you. Schematics will be provided then.

If it is possible, send me an email with your shipping address in order to post the PCB to you when I get them.

I may have 10 PCBs for free evaluation.

Have a nice weekend.

I designed isolator footprints for both NVE and SiLabs. You can use either of them on each position. Kind of backdoor again .

They come from different technologies. NVE has chip transformers, while SiLabs is based on CMOS capacitors. For FIFO application, only isolation performance will be important. Of course SiLabs is less expensive (at least from digikey ).

Nice weekend.

count me in for trial of pcb

Fortunately isolators from ADI have compatible pins and footprint, I think they could be use also on this PCB.

I suppose if the result is positive, everyone with a FIFO board would want one and you'll manufacture them in quantities...

Thanks. I think supplying PCB would be better , it's not that diffcult to solder this board.

To isolating the DAC from front end ground is a good idea. Many high speed ADC or DAC did this way.

Nice weekend.
