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.

•

Pin Compatible with STAC9700/21/56

100% Compatible with STAC9750/52

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.

KEY SPECIFICATIONS

•

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
