DATA SHEET 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” 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 and resulting in increased quality of voice applications. STAC9250/9251 Integrated modem functionality from Silicon Labs1 supports reduced BOM costs 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 FEATURES High-integration HD Audio Product 2-channel PC Audio CODEC Modem “System-side” functionality1 Dual Digital Microphone interface(STAC9251) Two-Channel DACs and ADCs with 24-bit sample resolution Integrated Headphone Amps Stereo Analog Microphone ……
