Replacement suggestions for ADAU1761 on TDM

we built a circuit with two ADAU1761 codecs sharing the digital serial audio bus as considered in the datasheet.

After searching the engineerzone we found:

The problem is the non-tri-statable ADC_SDATA pin on the ADAU1761. Even setting internal pull-ups does not work.

Is there a pin compatible codec to replace the ADAU1761 ICs with TDM bus support, or is complete redesign required?

Are there any other suggestions with minimum effort to make TDM work with ADAU1761?


Thanks in advance.


Best regards,
