Overview
SigmaTel, Inc.
Integrating Mixed-Signal Solutions Multimedia Audio Codec for AC’97 STAC9704/7 GENERAL DESCRIPTION: SigmaTel’s STAC9704/07 is a general purpose 18-bit, full duplex, audio codec that conforms to the analog component specification of AC’97 (Audio Codec ’97 Component Specification rev.
1.
03).
The STAC9704/07 incorporates SigmaTel’s proprietary Sigma-Delta technology to achieve signal quality in excess of 95dB SNR.
The DACs, ADCs, and mixers are integrated with analog I/Os, which include four analog line-level stereo inputs, two analog line-level mono inputs, and 3 output channels.
Also included are SigmaTel’s 3D stereo enhancement (SS3D) and an extra true line-level out for headphones or speaker amplifiers.
The STAC9704/07 communicates via the five wire AC Link to any digital component of AC’97 providing flexibility in the audio system design.
Packaged in a small AC’97 compliant 48-pin TQFP, the STAC9704/07 can be placed on the motherboard, daughter boards, add-on cards, PCMCIA cards, or outside the main chassis such as in a speaker.
The 9707 is identical to the 9704 except that the 9707 is tested at AVdd = DVdd = 3.
3V.
