Need info on SSM2604

Hi,

We have a product Slingbox350 which uses SSM2604 as the audio decoder.

Please let us know the format of I2S digital output data on pin 18(SDIN) when it is configured in ADC mode. We would like to know if the data output from pin 18 is raw data or 2's complement of raw data.

Regards,

Fayaz
