David,

Have you designed and built a PCB before?
If you haven't, I would suggest ordering a evaluation board. You get schematics, manuals, to help you along.
Then you can try copying the evaluation board design, if you like to get experience in building a PCB.(It's not as easy as it looks, try soldering 52 or more pins at 0.05 in. spacing). As a beginner you have to crawl before you can walk. If you order the evaluation board, at least you have a schematic of a proven design.
