Multi-channel Ac97 Codec With Multi-codec Option

SigmaTels STAC9708 STAC9711 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 SigmaTels 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 SigmaTels 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 STAC9711 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. By Unkown
