FEATURES • High performance Σ∆ technology • 6-Channel AC’97 2.3 CODECs • 20-bit full duplex stereo ADCs • 20-bit full duplex DACs • Headphone drive capability • SPDIF_IN Support • SPDIF_OUT Support, including 96 kHz • ADAT ® Optical “Litepipe” Interface Support • Universal JacksTM Functionality for jack interchangeability • Internal Jack Sensing • Crystal Elimination Circuit • Front/Rear Stereo Microphone • 96 kHz DAC Playback support • Up to 5 General Purpose I/Os • Digital and Analog PC BEEP • AC’97 2.3 Paging Registers and Analog Plug and Play Capability • Energy saving dynamic power modes • >90 dB SNR and >-90dBV THD+N • Adjustable VREF_OUT Control • Pin compatible with 2-Channel CODECs • Independent sample rates for ADC & DACs • +3.3 V & +5 V analog power supply options DESCRIPTION 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 Σ∆ 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. Supported ADC and DAC audio sample rates include 96kHz, 48kHz, 44.1kHz, 32kHz, 22.05kHz, 16kHz, 11.025kHz, and 8 kHz; additional rates are supported in the STAC9758/9759 soft audio drivers. All ADCs and DACs operate at 20-bit resolution. SPDIF_OUT supported sample rates include 96kHz, 48kHz, 44.1kHz and 32kHz. SPDIF_IN supports 48kHz and 44.1kHz. The STAC9758/9759 includes internal jack sensing using proprietary IDT current and impedance-sensing tech- niques. The impedance load on any of the inputs or outputs can be detected. The STAC9758/9759 also supports Uni- versal JacksTM functionality for jack interchangeability. The GPIOs on the STAC9758/9759 remain available for advanced configurations. The STAC9758/9759 can sup- port up to 5 GPIOs. The STAC9758/9759 is designed primarily to support 6-channel audio. Additionally, the STAC9758/9759 pro- vides for a stereo enhancement feature, IDT Surround 3D (SS3D). The STAC9758/9759 also supports the ADAT® Optical “Litepipe” Interface, which provides an 8 channel output for professional and consumer audio applications. The STAC9758/9759 can be SoundBlaster ® and Windows Sound System ® compatible when used with IDT’s WDM driver for Windows 98/2K/ME/XP or with Intel/Microsoft driver included with Windows 2K/ME/XP.
