DATASHEET  
HIGH-PERFORMANCE 6-CHANNEL AC’97  
2.3 CODEC WITH UNIVERSAL JACKS™  
STAC9758/9759  
OVERVIEW  
DESCRIPTION  
High performance, 6-channel, AC’97 2.3 CODECs with  
high Signal-to-Noise ratio and low distortion.  
IDT's STAC9758/9759 are general purpose 20-bit, full  
duplex, 6-Channel audio CODECs conforming to the ana-  
log component specification of AC '97 (Audio Codec 97  
Component Specification Rev. 2.3). The STAC9758/9759  
incorporates IDT's proprietary SD technology to achieve a  
DAC SNR in excess of 90dB. With IDT’s headphone drive  
capability, headphones can be driven without an external  
amplifier. The STAC9758/9759 communicates via the five  
AC-Link to any digital component of AC '97, providing flexi-  
bility in the audio system design. Packaged in an AC '97  
compliant 48-pin TQFP, the STAC9758/9759 can be  
placed on the motherboard, daughter boards, PCI, AMR,  
CNR, MDC or ACR cards.
