Topic: Has anyone used a Babyface with an ADI-4 DD for AES EBU?

I was wondering if someone has tested or used a Babyface with an ADI-4 DD to convert the adat optical to AES/EBU.
I think I read somewhere that someone experienced clocking issues because of the optical cable, though I'm not sure.
I'm especially interested how well this works with higher sample rates.
