STAC9708 Datasheet | SigmaTel

DESCRIPTION : Sigma Tel’s STAC9708/11 is a general purpose 18-bit, full duplex, audio codec that conforms to the analog ponent specification of AC'97 (Audio Codec 97 ponent Specification Rev. 2.1). The STAC9708/11 incorporates Sigma Tel’s proprietary Sigma-Delta technology to achieve a DAC SNR in excess of 95d B. 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 Sigma Tel’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 municates via the five-wire AC-Link to any digital ponent of AC'97 providing flexibility in the audio system design. Packaged in an AC'97 pliant 48-pin TQFP, the STAC9708/11 can be placed on the motherboard, daughter boards, add-on cards or PCMCIA cards.
