TWO-CHANNEL HD AUDIO CODEC WITH MODEM
& DUAL DIGITAL MICROPHONE INTERFACES
STAC9250/9251
DESCRIPTION
The STAC9250/9251 are high fidelity, 2-channel audio CODECs
compliant with the High Definition Audio (HD Audio) specification
defined by Intel. The STAC9250/9251 enables a two-chip audio
and modem implementation by integrating the “System Side”
functionality of Silicon Labs’ modem solution. The STAC9250/
9251 provides a direct interface to Silicon Labs’ “Line Side” inte-
grated circuit. This integration results in cost savings without sac-
rificing audio fidelity or modem functionality. The STAC9251 also
implements a direct interface to two digital microphones, support-
ing advanced beam forming applications and resulting in
increased quality of voice applications.
