1. The codec is partitioned into a digital and analog
sections to help isolated noisy digital circuitry form
quiet analog circuitry.
2. The layout separates the analog and digital planes
with a 60 to 100 mils gap and connect them at one
point beneath the codec with a 50 mils wide blink.
3. Never route digital traces or digital planes under
the analog ground areas. Analog components should be
located over analog planes (ground and power planes)
and digital components should be located over digital
planes.

1. Close to codec.
2. Realtek suggested
that layout trace of
the sense pin should
away form any analog
trace because sensing
current might
distorts the audio
performance (The
bottom lay is best
choice).
