TWO-CHANNEL HD AUDIO CODEC WITH MODEM

& DUAL DIGITAL MICROPHONE INTERFACES

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.
