Pinout M-Tek D4101DAG??

[wgh52]

Hello everyone,

I'm looking for the pin-out or datasheet of an M-Tek D4101DAG which is obviously a pulse transformer used to drive SPDIF 75Ohm lines. I couldn't find anything on the web about it, but want some data and the pin-out because I want to re-use the parts on a miniDSP nanoDIGI board.

Thanks for any help!

1 is input, 2 is inputs GND, I am sure of that. 3 seems to be the output and 4 outputs GND (for right phasing). You can put signal on the input pins and measure the outputs. The transformer seems a clone of the Pulse Engineering types. I think you better look for Murata DA-101C if you like known good quality.

Thanks for your prompt answer! The old devices are in a working circuit which I try to understand and your description confirms my suspicion, so this helps!

Thanks again,
Kind greetings,
Winfried
