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.
