Interfacing ADAU1701 with AD1955 (2)

As a bit of a continuation from Interfacing ADAU1701 with AD1955

 

Has anyone successfully used an ADG3304 for I2S level translation from an ADAU1701? Or could anyone offer an educated/experienced guess perhaps, as to the feasibility. Dr. Ram expressed concerns about the ADAU1701's drive voltage, I noticed he said he'd try it and post back if it worked...and didn't! (May well have forgotten though).

 

When buffering the OSCO output should there be a 3.3V to 5V level translation happening? (Fairly new to digital and clocks so apologise if this is basics, couldn't find an answer elsewhere though). Perhaps this could be done with the 4th channel of the ADG3304?

 

Thanks again.
