Default S/PDIF Digital output

Hi all,

I have an Arcam Alpha 5 working only as a transport. I built a new digital output with a new Pulse transformer (see att. picture).

Any comments or suggestions are very welcome.

I have already done that, many times, but let's start here:

What is the ouptput impedance?

Ops... that signal is not attenuated to SPDIF (0.5V p-p) level...
Impedance? Not 75R for sure.

At least 2 of you guys have been paying attention.............

OK, assuming that he fixes those problems, what transformer is it?? All pulse transformers are not created equally. Most are useless for SPDIF.

If you don't believe me, try the one that comes stock in Philips CPDs. Designed to minimise EMI, not performance.

Hi,


Jocko Homo:

Pulse transformer is a PE-65612.

The original schematic will be better?
