Reference Designs  
FEATURES  
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-
