Teflon has lower DA and DF than Delrin. Remember, we are talking femtoseconds here. Regards

BTW, since I am not an expert in high speed transmission lines, what length cable would you suggest? Thanks and regards

Femtoseconds? Really? And how does that relate to DA and DF?

Dave, your turn. Much Kool-Aid here.

I am ready and eager to learn more about digital transmission, but I had been lead to believe that any "echoes" of the signal would cause jitter. Those who work in these realms are invited to provide instruction. Regards

You didn't specify if you need 75 ohm or 50 ohm. That is orders of magnitude more important to your signal than the dielectric material at any frequency, and especially at the frequencies used for your application (which you also didn't specify but did mention in a later post).

It is 75ohm for SPDIF transmission between a jitter reduction device and DAC. Regards

I'm not entirely convinced that we are even talking nanoseconds here. And of course the receiver chip will have a clock recovery PLL to filter off high frequency jitter. S/PDIF can survive relatively unscathed after passing through an RCA connector (complete mismatch, although fortunately short) so a short length of correctly terminated cable with ordinary decent quality BNC connectors will do no harm.

"Straining at gnats" is the phrase which comes to mind. If you are really worried about jitter then your jitter reduction circuit needs to be next to the DAC chip, as I said earlier.

To prevent or damp-out reflections, use the proper value of termination resistor, wherever needed. See the simple practical procedure for doing that in the post linked here:

paralleling film caps with electrolytic caps

Cheers,
