unknown numbers schematic ADAU1442 evalboard

Hey,

I want to start designing my PCB for the DSP  soon. I tried to understand whats happening around the DSP on my ADAU  1442 EvalBoard.

I found some numbers in brackets in the schematic that confuse me. You can see it at the picture "numbers". It comes from the userguide for the ADAU1442 EvalBoard (UG-032).

Can anyone help me.

Thanks,

Christian
