Hi Thomas-san,

The TI solution which accepts upto 192kHz SPDIF and converts it to 24bit I2S controlling via I2C bus is PCM9211 with the 96kHz stereo ADC.
The reverse conversion mentioned above is also possible.

Best regards,
Kato

does this mean we need two (one for each direction ?)

Hi Thomas-san,

The mutual conversion is possible simultaneously using one PCM9211.
Please refer to PCM9211 data sheet for details.

Best regards,
Kato
