1 / 56 page  1 10/02/98 PRELIMINARY SigmaTel, Inc. Integrating Mixed-Signal Solutions STAC9708/11 Multi-Channel AC'97 Codec With Multi-Codec Option GENERAL DESCRIPTION: SigmaTel’s STAC9708/11 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. 2.1). The STAC9708/11 incorporates SigmaTel’s proprietary Sigma-Delta technology to achieve a DAC SNR in excess of 95dB. The DACs, ADCs, and mixer are integrated with analog I/Os, which include four analog line-level stereo inputs, two analog line-level mono inputs, two stereo outputs, and one mono output channel. Also included are two additional high quality DACs, with independent volume control, for multi-channel applications. With SigmaTel’s 3D stereo enhancement (SS3D), independently selectable on both LINE OUT and DAC OUT, the multi-channel mode immerses the user in a richer and livelier listening experience. The STAC9708/11 may be used as a secondary codec, with the STAC9704/07 as the primary, in a multiple codec configuration conforming to the AC'97 Rev. 2.1 specification. This configuration can provide true six-channel, AC-3 playback required for DVD applications. The STAC9708/11 communicates via the five-wire AC-Link to any digital component of AC'97 providing flexibility in the audio system design. Packaged in an AC'97 compliant 48-pin TQFP, the STAC9708/11 can be placed on the motherboard, daughter boards, add-on cards or PCMCIA cards. FEATURES: • High performance ΣΣ∆∆ technology • Two additional high quality DAC’s for multi-channel applications • 18-bit full duplex stereo ADC, DACs • AC-Link protocol compliance • Multiple power supply options • Pin compatible with the STAC9704/07 • SigmaTel Surround (SS3D) Stereo Enhancement • Energy saving power down modes • Multi-Codec option (Intel AC'97 rev 2.1) • Six analog line-level inputs • 48-pin TQFP • SNR > 95 dB through Mixer and DAC |
