FEATURES

DESCRIPTION

For Rev. CC1 parts and beyond

High performance Σ∆ technology

AC’97 Rev 2.3 Complaint

SigmaTel’s STAC9766/67 (Revision CC1 and

beyond) are general purpose 20-bit, full duplex,

audio codecs conforming to the analog compo-

nent specification of AC’97 (Audio Codec 97 Com-

ponent Specification Rev. 2.3). The STAC9766/67

incorporates SigmaTel’s proprietary Σ∆ technol-

ogy The AC’97 codec is designed to achieve a

DAC SNR in excess of 103dB. 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. The STAC9766/67

includes digital input/output capability for support

of modern PC systems with an output that sup-

ports the SPDIF format. The STAC9766/67 is a

standard 2-channel stereo codec. With SigmaTel’s

headphone drive capability, headphones can be

driven with without an external amplifier.

General purpose I/O

The STAC9766/67 may be used as a secondary

codec, with the STAC9700/21/56/08/84/50/52 as

the primary, in a multiple codec configuration con-

forming to the AC'97 Rev. 2.3 specification. This

configuration can provide true six-channel, AC-3

playback required for DVD applications. The

STAC9766/67 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 STAC9766/

67 can be placed on the motherboard, daughter

boards, PCI, AMR, CNR, MDC or ACR cards.
