Need an opinion on SPDI/F transformer from C & D TECHNOLOGIES

I am building three SPDI/F outputs in my Sony N975 DVD player. I found this transformer that seems to fit the bill, but I have no direct experience with the company that makes them. The company is C & D TECHNOLOGIES and the transformer part number is DA101M/R. Here is the link

How good is this device for SPDI/F application?

Thanks
 
Jocko,

Thanks for the reply. I am sorry about the link, I think this one should work

Newark does have stock, here is the link

I think I will go ahead and get those transformers. THey are a lot cheaper by a factor of nearly 10, then the Newava line at Digi-key.


What do you think of Pomona BNC plugs like this one

1.67 dollar, is that possible?

Well gentlemen,

Yes, it is hard to believe, but they are only $1.67! In fact I found prices at Newark to be quite reasonable.

Anyway, since we are on the topic of transformers, - what do I do if I want to connect a 75 Ohm source from RCA jack to a 110 Ohm target on XLR jack? Do I simply get me a 75-110 Ohm transformer? Of yes, then which one? Or, should I built a circuit that will do the same thing with logic gates? I think the voltage level of the SPDI/F from my source is high enough for the 110 Ohm target.

Right now I am simply using a RCA to XLR cable with pins 1 and 3 connected together and hooked to the shield on the XLR side and it works, but I know it is not a right thing to do.

Thanks
