we have a product that utilizes the ADAU1452. It would be a nice feature to have AES3 support, although it is not a main objective.
The datasheet of the ADAU1452 states specifically that AES3 is not supported by the SPDIF interface of the ADAU1452, but it does not specify why this is the case.
Would it at least be possible to use the SPDIF receiver with an external RS422 receiver and a proper signal transformer to listen to AES3 signals? If this is not possibe, can anybody explain to me the reason why?
