DATASHEET  
TWO-CHANNEL, 20-BIT, AC’97 2.3 CODECS WITH HEADPHONE STAC9752/9753  
DRIVE, SPDIF OUTPUT MICROPHONE & JACK SENSING  
5-wire AC-Link protocol compliance  
20-bit SPDIF Output  
Description  
IDT's STAC9752/9753 are general purpose 20-bit, full  
duplex, audio CODECs conforming to the analog  
component specification of AC'97 (Audio CODEC 97  
Component Specification Rev. 2.3). The STAC9752/9753  
incorporate IDT's proprietary SD technology to achieve a  
DAC SNR in excess of 90dB. 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  
STAC9752/9753 include digital output capability for support  
of modern PC systems with an output that supports the  
SPDIF format. The STAC9752/9753 are standard  
2-channel stereo CODECs. With IDT’s headphone  
capability, headphones can be driven without an external  
amplifier. The STAC9752/9753 may be used as a  
secondary or tertiary CODECs, with STAC9700/21/44/56/  
08/84/50/66 as the primary, in a multiple CODEC  
configuration conforming to the AC'97 Rev. 2.3  
specification. This configuration can provide the true  
six-channel, AC-3 playback required for DVD applications.  
The STAC9752/9753communicate via the five AC-Link  
lines to any digital component of AC'97, providing flexibility  
in the audio system design. Packaged in an AC'97  
compliant 48-pin TQFP, theSTAC9752/9753 can be placed  
on the motherboard, daughter boards, PCI, AMR, CNR,  
MDC or ACR cards.
