DESCRIPTION
SigmaTel's STAC9758/59 general purpose 20-bit, full duplex, 6-Channel audio codecs conforming analog component specification AC'97 (Audio Codec Component Specification Rev. 2.3). STAC9758/59 incorporates SigmaTel's proprietary technology achieve excess 90dB. With SigmaTel's headphone drive capability, headphones driven without external amplifier. STAC9758/59 communicates five AC-Link digital component AC'97 providing flexibility audio system design. Packaged AC'97 compliant 48-pin TQFP, STAC9758/59 placed motherboard, daughter boards, PCI, AMR, CNR, cards. Supported audio sample rates include 96kHz, kHz, 44.1 kHz, kHz, 22.05 kHz, kHz, 11.025 kHz, kHz; additional rates supported STAC9758/59 soft audio drivers. ADC's DAC's operate 20-bit resolution. SPDIF_OUT supported sample rates include 96kHz, 48kHz, 44.1kHz 32kHz. SPDIF_IN supports 48kHz 44.1kHz. STAC9758/59 includes internal jack sensing using proprietary SigmaTel current impedance-sensing techniques. impedance load inputs outputs detected. STAC9758/59 also supports Universal Jacksfunctionality jack interchangability.

GPIOs STAC9758/59 remain available advanced configurations. STAC9758/59 support upto GPIOs. STAC9758/59 implementation internal jack sense uses Extended Paging Registers defined AC'97 Specification. This allows additional registry space hold identification information about codec, jack sensing details results, external surroundings codec. information within Extended Paging Registers will allow automatic configuration audio subsystem without end-user intervention. example, BIOS populate Extended Paging Registers with valuable information both audio driver operating system such gain attenuation stages, input population input phase jack location. With this input information, SigmaTel driver will automatically provide Volume Control Panel only volume sliders that implemented system, thus improving end-user's experience with information Extended Paging Registers will also allow automatic configuration microphone inputs, ability switch between SPDIF analog outputs, routing master volume slider proper physical output, SoftEQ configurations. fully parametric SigmaTel SoftEQ initiated upon jack insertion removal. STAC9758/59 designed primarily support 6-channel audio. Additionally, STAC9758/59 provides stereo enhancement feature, SigmaTel Surround (SS3D). STAC9758/59 also supports ADAT® Optical "Litepipe" Interface, which provides channel output professional consumer audio applications. STAC9758/59 SoundBlaster® Windows Sound System® compatible when used with SigmaTel's driver Windows 98/2K/ME/XP with Intel/Microsoft driver included with Windows ME/XP.
