W83971D Datasheet, PDF (58/58 Pages) Winbond – AC97 AUDIO CODEC

Preliminary W83971D
* The digital ground pins should be connected to the digital ground plane and kept
separate from any of the analog ground connections and analog circuitry.
* The common connection point between the two ground planes should be located near the W83971D
just under the digital ground connections.
* The AC-Link digital interface connection traces should be routed such that digital ground plane lies
underneath these signals from the AC97 controller continuously to the W83971D.
