DATA SHEET  
TWO-CHANNEL HD AUDIO CODEC WITH MODEM  
& DUAL DIGITAL MICROPHONE INTERFACES  
STAC9250/9251  
•
Integrated modem functionality from Silicon Labs1  
supports reduced BOM costs  
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.
