Google's first hit gets me the data sheet, this includes layout guidelines so what else do you need?
I certainly would not use a layout that someone else has done that is different to the datasheets' recommended layout as "reference".
I am using QFN package. TI has got evaluation design files for BGA package.
As of now I am trying to follow the layout guidelines suggested on the datasheet. It would be nice if I can get some one's design as a reference.
