I highly recommend that book.  It's extremely practical.  Unlike most
electronics books that can't say anything truly meaningful without
slipping into differential equations, this keeps everything at a very
accessible level.

They specifically address the issue that appnotes always design simple,
single mixed-signal device PCBs and give no hint as to how to expand that
to a multi-chip design.

If you 'search inside' for 'split' and take the link that starts at page
873 you might be able to get what you want.
