High Performance SD Technology

AC’97 Rev 2.3 Complaint

DESCRIPTION

IDT's STAC9752A/9753A are general purpose 20-bit, full

duplex, audio CODECs conforming to the analog compo-

nent specification of AC'97 (Audio CODEC 97 Component

Specification Rev. 2.3). The STAC9752A/9753A incorpo-

rates IDT's proprietary SD technology.

20-bit Full Duplex Stereo ADC & DACs

Independent Sample Rates for ADC & DACs

5-Wire AC-Link Protocol Compliance

20-Bit SPDIF Output

Universal Jacks^™

The AC’97 CODEC is designed to achieve a DAC SNR in

excess of 94dB. The DACs, ADCs, and mixer are inte-

grated 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.

Full Stereo Microphone Pre-Amp

Internal Jack Sensing on Headphone & Line_Out

Internal Microphone Input Sensing

Digital PC Beep Option

The STAC9752A/9753A includes digital input/output capa-

bility for support of modern PC systems, with an output that

supports the SPDIF format. The STAC9752A/9753A is a

standard 2-channel stereo CODEC. With IDT’s headphone

drive capability, headphones can be driven with without an

external amplifier.

Extended AC’97 2.3 Paging Registers

General Purpose I/Os and Crystal Elimination

Circuit

Headphone Drive Capability (50 mW per channel)

Switchable Headphone Out (pins 39/41 or 35/36)

The STAC9752A/9753A may 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.

0dB, 10dB, 20dB and 30dB Microphone Boost

Capability

•

+3.3 V (STAC9753A) and +5 V (STAC9752A) Analog

Power Supply Options

Pin Compatible with STAC9750/52/66

The STAC9752A/9753A communicates via the five-wire

AC-Link to any digital component of AC'97, providing flexi-

bility in the audio system design.

KEY SPECIFICATIONS

•

Analog LINE_OUT SNR: 94dB

Digital DAC SNR: 92dB

Packaged in an AC'97 compliant 48-pin TQFP, the

STAC9752A/9753A can be placed on a motherboard,

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

Digital ADC SNR: 85dB

Full-scale Total Harmonic Distortion: 0.002%

Crosstalk Between Input Channels: -70dB

Spurious Tone Rejection: 100dB

Stereo Microphone Input

The STAC9752A/9753A provides variable sample rate Dig-

ital-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 STAC9752A/9753A soft

audio drivers. All ADCs and DACs operate at 20-bit resolu-
