1. DESCRIPTION
IDT™
TWO-CHANNEL HD AUDIO CODEC WITH MODEM & DUAL DIGITAL MICROPHONE INTERFACES
STAC9250/9251
TWO-CHANNEL HD AUDIO CODEC WITH MODEM & DUAL DIGITAL MICROPHONE INTERFACES
1.1.
1.2.
1. Modem functionality can only be used with a “Line Side” DAA integrated circuit, Si3080 or similar, available from Silicon Labs
(www.silabs.com).
Overview
Features
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 solu-
tion. The STAC9250/9251 provides a direct interface to Silicon Labs’ “Line Side” integrated circuit.
This integration results in cost savings without sacrificing audio fidelity or modem functionality. The
STAC9251 also implements a direct interface to two digital microphones supporting advanced beam
forming applications resulting in increased quality of voice applications.
