DESCRIPTION  
20-bit Full Duplex Stereo ADC & DACs  
Independent Sample Rates for ADC & DACs  
5-Wire AC-Link Protocol Compliance  
20-bit SPDIF Output  
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).  
Full Stereo Microphone Pre-Amp  
Internal Jack Sensing on Headphone & Line_Out  
Internal Microphone Input Sensing  
Digital PC Beep Option  
The STAC9766/9767incorporates IDT's proprietary SD  
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.  
Extended AC’97 2.3 Paging Registers  
Digital-ready Status  
General Purpose I/O  
Crystal Elimination Circuit  
Headphone Drive Capability (50 mW)  
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.  
0dB, 10dB, 20dB and 30dB Microphone Boost  
Capability  
•
+3.3 V (STAC9767)and +5 V (STAC9766) Analog  
Power Supply Options  
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.

IDT Surround (SS3D) Stereo Enhancement  
Energy Saving Dynamic Power Modes  
Multi-CODEC Option (Intel AC'97 rev 2.3)  
Six Analog Line-level Inputs  
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.  
103dB SNR LINE-LINE  
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.

Analog LINE_OUT SNR: 103 dB  
Digital DAC SNR: 95 dB  
The STAC9766/9767provides variable sample rate Digi-  
tal-to-Analog (DA) and Analog-to-Digital (AD) conversion,  
mixing and analog processing.  
Digital ADC SNR: 85 dB  
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.  
Full-scale Total Harmonic Distortion: 0.002%  
Crosstalk Between Input Channels: -70 dB  
Spurious Tone Rejection: 100 dB  
The STAC9766/9767 includes full Stereo Microphone
