digital transformer

[mikelm]

any one know where I can get a digital transformer or two from ?

apart from here:

I assume you mean a pulse transformer, for SPDIF coupling? Try Newava S22083, available at digikey.

 

[mikelm]

thanks - that is exactly what I mean

Thanks Peter

how about Sprague 11z2000

anybody used that pulse transformer
can be better than the newava

That transformer appears to be designed for HV lighting, not digital audio.

I use Mini-Circuits ADT1-6T.

It doesn't have enough current handling to meet the AES/EBU spec without terminating the input side of the transformer, but it's perfectly fine for SPDIF.

Just please don't use an Ethernet transformer...

PE65612 from digikey/mouser are also decent. the newava is supposed to be better.

 

[samoloko]

I don't think that digikey has pe-65612

Mouser has these.

C&D Technologies.

Anyone try them? Three different parts with windings for the different pulse widths.

update...

I have tried the DA101C. Data sheet in the message above.

It's available from Mouser. It works OK for 44.1 to 192K. I haven't given it an exaustive test.

It's cheaper than the Newava at Digikey.

Forgive my ignorance. What's wrong with an ethernet transformer?

The best ones are from Scientific Conversion. I used them in all my circuits and they are really good.

Jon from SC was our guest this year at the Burning Amp, and he demonstrated his jitter measurement and comparison of various digital transformers. You could clearly see the difference between various digital transformers in regards to his own.

 

[rossl]

The last time I talked to Scientific Conversion, they had a minimum order of 25 transformers.

Please send me email, I will be happy to help you.

Sorry to bring up this old thread.

Anyone who has purchased small quantities from SC, can they please share their price quotes? I'm just looking for ballpark pricing, e.g. $10/ea.

Thanks!
