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.  
Interfaces directly to Line Side integrated circuit from  
Silicon Labs  
Supports two-chip audio plus modem functionality  
Supports Software modem implementations from  
Motorola and others compatible with the Silicon Labs  
chipset  
Supports Motherboard implementations eliminating MDC  
card and connector costs  
Reduced board space  
Reduced external component count
