PCM5102A circuit components

I've gotten my hands on a pair of PCM5102A chips and want to create a DAC for my rpi. So my project is sort of Hifiberry DAC DIY.

I've looked through TI's reference diagrams (http://tinyurl.com/owh3rjz, PCM51xx, p. 26). The components here are pretty straight forward (maybe except the 10nf). What did you learn through your dev. phase? Any alterations from the reference?

Further, what component did you use for the 5V->3.3V transformation?. This component seems to have changed trough the revs.

Br,
Andreas
