Thanks, Yagami.
Hi Adam,
The circuit on the ADAU1442 eval board can be copied to any S/PDIF input; it is important to provide a 75 ohm load to the incoming signal because the S/PDIF input on the ADAU1442 is hi-z, and AC coupling is necessary for the S/PDIF input. The ADAU1452 has the same requirement.
Best regards,
Coleman
