Dunno how people are implementing ADAT now?
Also interested, just curiosity, wavefront second hand are very overpriced, but in any case, extinct IC with manage a very simple protocol, obsolescence because the niche is addressed to better solutions (MADI/AVB) but I still enjoy my "old" RayDAT and want for many years to interconnect my adat gear.
Maybe looking into a new Behringer item as adat 8200, but I guess that use custom ic's paying Alesis royalties.
It is more likely that a recent Motu, with AVB that means new platform&dev.board, unveil a generic ic programmed to ADAT trans/decode.
About AVB.
I took a few months looking AVB solutions, I am interested in soft. development. Now some pro-solutions AVB (also have Adat) come from Motu.
But in terms of development, check Xmos platform, a good AVB platform.
#Richard -> Xmos had ADAT in their roadmap for some time, maybe they have it now.
