Layout considerations for Tuner, Audio Amp & Audio proce

[san2004]

Hi Frnds,

Currently I am working on one project which is having Tuner, Audio Amplifier & Audio processor alongwith other digital sections on main board.Main processor is Genesis Chip. This is 4 layers board. While doing layout what precautions we have to take to avoid any crosstalk, noise related issues ?
If there any guidelines or notes for above mentioned sections pls share.

Thanks in Advance,
Byee !!!

Separate the analog and digital planes ,don't overlap.
Keep more space between analog and digital signals.
Put analog reference for analog signals and digital reference for the digital signals.
