Barrows, they are used because of cost not quality or for signal integrity, I spend all day designing PCBs putting together systems and we would not dreem of using a ribbon cable.
I cant see why you wanna argue the fact, why not go do some reseach, have a look at what connectors etc are being used.
To properly control the impedance of the interconnect you either use a FFC cable or design a bespoke flexible PCB or cable assembly.
Again if you are DIYing why not try and use the BEST methods available...

Hi
Marce: I am not trying to argue anything, just pointing out that you were wrong to suggest that ribbon cables are not used for this purpose, and in very well respected , very expensive, high end products as well. Considering that some dCS products are pretty much built to cost no object standards, I truly wonder how much real world difference there would be between 5 cm of ribbon cable, and something else when well implemented. My understanding is that there is no impedance spec for I2S, becuse it is designed for very short distances where reflections will not be an issue: is this understanding incorrect?
What is FFC? Are you talking about coax like u.fl, or?

Hi,
At AMR we use ribbon cables in a number of places. They provide as good or better signal integrity as PCB's if used and specified correctly.
Our ribbon cable cable for signal use is solid core copper with silver plating and PTFE insulation and have at least as precise impedances as you can practically get with strip lines.

Hello Lorien, i wonder what happened to your Board?
have you got it finished yet?
cheers
