DATASHEET  
VALUE-LINE TWO-CHANNEL AC’97 CODECS  
STAC9750/9751  
OVERVIEW  
DESCRIPTION  
Value-Line Stereo AC'97 CODECs with headphone drive  
and SPDIF outputs.  
IDT's STAC9750/9751 are general purpose, full duplex,  
audio CODECs conforming to the analog component spec-  
ification of AC'97 (Audio CODEC 97 Component Specifica-  
tion Rev. 2.2). They have 18-bit ADCs and 20-bit DACs.  
The STAC9750/9751 incorporate IDT's proprietary Σ∆ tech-  
nology to achieve a DAC SNR in excess of 89dB.  
FEATURES

•
Full Duplex Stereo 18-bit ADCs and 20-bit DACs  
AC’97 Rev 2.2 Compliant  
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.  
High Performance Σ∆ Technology  
SPDIF Output  
Crystal Elimination Circuit  
Headphone amplifier  
The STAC9750/9751 include digital input/output capability  
for support of modern PC systems and also an output that  
supports the SPDIF format.  
Independent Sample Rates for ADCs & DACs  
(hardware SRCs)  
The STAC9750/9751 is a standard 2-channel stereo  
CODEC. With IDT’s headphone drive capability, head-  
phones can be driven with no external amplifier.

20dB or 30dB Microphone Boost Capability  
90dB SNR LINE-LINE  
5-Wire AC-Link Protocol Compliance  
Digital-Ready Architecture  
The STAC9750/9751 may be used as a secondary  
CODEC, with the STAC9700/21/44/56/08/84/66 as the pri-  
mary, in a multiple CODEC configuration conforming to the  
AC'97 Rev. 2.2 specification. This configuration can provide  
the true six-channel, AC-3 playback required for DVD appli-  
cations.  
General Purpose I/O  
+3.3 V (STAC9751) and +5 V (STAC9750) Analog  
Power Supply Options  
•
•
•
Pin Compatible With STAC9700/21/56/66  
IDT Surround (SS3D) Stereo Enhancement  
Energy Saving Dynamic Power Modes  
The STAC9750/9751 communicates via the five-wire  
AC-Link to any digital component of AC'97, providing flexi-  
bility in the audio system design.  
The STAC9750/9751 supports General Purpose Input/Out-  
put (GPIO), as well as SPDIF output. These digital I/O  
options provide for a number of advanced architectural  
implementations, with volume controls and digital mixing  
capabilities built directly into the CODEC.  
KEY SPECIFICATIONS

•
Analog LINE_OUT SNR: 90dB  
Digital DAC SNR: 89dB  
Digital ADC SNR: 85dB  
Packaged in an AC'97 compliant 48-pin TQFP, the  
STAC9750/9751 can be placed on the motherboard,  
daughter boards, PCI, AMR, CNR, or ACR cards.  
Full-scale Total Harmonic Distortion: 0.005%  
Crosstalk between Input Channels: -70dB  
Spurious Tone Rejection: 100dB
