Filter select and Format select pins can't be left not connected IMO.
Read the PCM5102 datasheet

ICs' datasheets tell you all. Read them carefully.

Hi ionutzxpo,

Perhaps this schematic will help you.

Hello,
the PCM2707 only supports up to 44,1 khz with 16 bit. Is there also an usb interface avaible supporting 384 khz with 32 bit because the PCM5102 also does? Then cd audio could be resampled to octuple and would sound much smoother.
Thank You!

The Tenor 7022L does 24bit/96KHz, but it's almost impossible to get ahold of if you don't plan on buying 100,000 pieces.

hmmmm, upsampling x8 automatically makes it so much smoother with little effort? get it right at 16/44.1 first. layout becomes more and more critical as the frequency goes up, it doesnt become easier to get good sound
