Re: Audio Codec layout

For audio codec layout , need care about following things ;
(1) For 2 channel codec , symmetric layout should be done.
(2) Separate digital/analog power /ground is must.
(3) More guard-ring to avoid noise coupling .
(4) More ground/power lines for each analog block is better.
