STAC9704/7

Multimedia Audio Codec for AC’97

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.
