AES/EBU transformers?

gmarsh · 7th April 2004, 12:59 PM

We're looking for a 32-96KHz (192khz would be sweet, but we need 32KHz) AES/EBU isolation transformer, for a board we're building at work. SMT is preferable, but optional.

Right now we use the Scientific Conversion SC937-02 part on another board, but purchasing is telling me the part is becoming difficult/expensive to get.

Pulse makes a "CS8402 recommended" part (PE-65812) but they don't reveal much about the part itself and since the CS8402 is a 48KHz part, I'm concerned about its performance. And Pulse hasn't answered any of my e-mails yet. Schott also makes a bunch of transformers, but their website is broken (sql server errors) so I can't really find out much about their offerings.

There's probably some extremely common, decent, inexpensive part that everyone uses, I just want to find it

any suggestions?

Thanks!

I heard that Schott had gone under - could be why you have no luck with there web site... But I'm not 100% sure...

Pulse make some of the better parts - so I guess there transformers should be good for 192KHz.

Bandwidth: 100 kHz - 55 MHz

Some of the Newava stuff seems to work well to at least 96kHz, and is readily available from Digikey. IIRC the Newava pn is S22160 and this is what I am currently using. It is supposed to be equivalent to the Schott 22160. (This is intended for spdif use, but they do have AES/EBU targeted variants and even this one probably works fine with AES/EBU amplitudes.)
