DESCRIPTION
IDT's STAC9766/9767 (Revision CC1 and beyond) are
general purpose 20-bit, full duplex, audio CODECs con-
forming to the analog component specification of AC'97
(Audio CODEC 97 Component Specification Rev. 2.3).
The STAC9766/9767incorporates IDT's proprietary Σ∆
technology 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 STAC9766/9767 includes digital
input/output capability for support of modern PC systems
with an output that supports the SPDIF format.
The STAC9766/9767 is a standard 2-channel stereo
CODEC. With IDT’s headphone drive capability, head-
phones can be driven with without an external amplifier.
The STAC9766/9767may be used as a secondary
CODEC, with the STAC9700/21/56/08/84/50/52 as the pri-
mary, in a multiple CODEC configuration conforming to the
AC'97 Rev. 2.3 specification. This configuration can pro-
vide the true six-channel, AC-3 playback required for DVD
applications.
The STAC9766/9767 communicates via the five-wire
AC-Link to any digital component of AC'97, providing flexi-
bility in the audio system design.
Packaged in an AC'97 compliant 48-pin TQFP, the
STAC9766/9767 can be placed on a motherboard, daugh-
ter boards, PCI, AMR, CNR, MDC or ACR cards.
The STAC9766/9767provides variable sample rate Digi-
tal-to-Analog (DA) and Analog-to-Digital (AD) conversion,
mixing and analog processing.
Supported audio sample rates include 48KHz, 44.1KHz,
32KHz, 22.05KHz, 16KHz, 11.025KHz, and 8 KHz; addi-
tional rates are supported in the STAC9766/9767 soft
audio drivers. All ADCs and DACs operate at 20-bit resolu-
tion.
The STAC9766/9767 includes full Stereo Microphone
