I've been looking around for an board, something like the CDB4272 or a circuit board that I can have made at JLCPCB or others, that would have two channels of balanced analog input with AESBU output, ideally, or I2S/SPDIF.
I have a lot of old recording equipment like DAT and ADAT that I like to use, but their ADCs are 30yrs old. I have a couple outboard ADCs but they are over 10yrs old too. I had thought about using the CDB4272 but that eval board is like $450 and I could probably draw the schematic and have my own made. I'm very good with micros of all types, have tons (literally) of test equipment so making a debugging isn't a big deal, just wondering if anyone already went this route and has a board posted someplace? Output needs to have 16bit at 48khz minimum and then selectable higher bit and sample rates. I also need the word clock output.
Thanks
Jerry

No idea about ADCs that're less than 10 years old but DIT4192 is a nice SPDIF (IEC-60958) chip if that helps, standalone, no microcontroller and the channel status bits are user controllable, if I understand correctly.
