11 / 126 page  STAC9200/9200D 2-CHANNEL HIGH DEFINITION AUDIO CODEC PC AUDIO IDT™ 2-CHANNEL HIGH DEFINITION AUDIO CODEC 11 STAC9200/9200D V 1.4 12/06 IDT CONFIDENTIAL 1. DESCRIPTION The STAC9200/9200D is a high quality, 2-channel audio CODEC compatible with the Intel High Definition (HD) Audio Interface (formerly known as “Azalia”). The STAC9200/9200D provides high quality, HD Audio capability to notebook and cost sensitive desktop PC applications. The STAC9200/9200D has been designed as a drop-in replacement for the STAC9772/73 Dual Mode (HD Audio and AC97) 2-channel CODEC once the need to support AC97 is eliminated. The STAC9200/9200D incorporates IDT's proprietary SD technology to achieve a DAC SNR in excess of 100dB. The higher performance and quality of IDT’s audio solutions brings consumer device level performance to the notebook, desktop and media center PCs. The STAC9200/9200D provides Stereo 24-Bit, full duplex resolution supporting sample rates up to 192 KHz by the DAC and ADC. The STAC9200/9200D DAC, ADC and SPDIF In/Out support sample rates of 96 KHz, 48 KHz and 44.1 KHz. Additionally, the SPDIF Out supports 32 KHz. The CODEC’s driver supports additional sample rate options. The STAC9200/9200D supports all desired two channel configurations, including switchable Headphone Out, and Universal JacksTM functionality for automatic jack detection sensing and retasking. The SPDIF interface provides connectivity to Consumer Electronic equipment like Dolby Digital decoders, powered speakers, mini disk drives or to a home entertainment system. All analog I/O pairs support LINE_IN, LINE_OUT and MIC. MIC inputs can be programmed with 0/10/20/30/40dB boost. For more advanced configurations, the STAC9200/9200D has four General Purpose I/O (GPIO) pins. The STAC9200/9200D also provides a single ended CD input to avoid DRM incompatibility and to support legacy OS issues. The STAC9200/9200D integrates a headphone amplifier which is available on Ports A and D. The headphone amplifier is switchable between these two outputs for increased flexibility, enhanced user experience, and reduced implementation costs. The Universal Jack capabilities allow the CODEC to detect when audio devices are connected to the CODEC, sense the type of device (LINE_IN, LINE_OUT, MIC, Headphone) that is inserted, and to allow the CODEC to be reconfigured to support these devices wherever they are plugged into the system. SPDIF input sensing is also supported. The fully parametric IDT SoftEQ can be initiated upon headphone jack insertion and removal for protection of notebook speakers. The STAC9200/9200D operates with a 3.3V digital supply and is available in either 5V, 4V or 3.3V analog sup- ply. The +4V Analog voltage is supported by the +5V version of the STAC9200 or STAC9200D appropriate configuration settings of the driver. The STAC9200/9200D is available in 48-pin LQFP and 32-pad QFN package options. The 32-pad QFN pack- age can be co-located inside the standard 48-pin footprint allowing systems to be designed to accept either version of the STAC9200/9200D or be compatible with existing 48-pin CODECs. Both the 48-pin LQFP and the 32-pad QFN are available in the ROHS compliant Lead (Pb) free package. The STAC9200/9200D is supported with IDT’s high quality software solutions which include drivers for all major Windows operating systems from Microsoft Parametric SoftEQ, and Digital Rights Management. Third party plugin capability is easily achieved with the IDT Kernel Processing Interface, to support high valued third party technologies like SRS WOW®, Knowles® Microphone Beam forming, Waves MaxxBASS®, Dolby Head- phone®, Dolby ProLogic II® and Dolby Virtual Speaker® and more. The STAC9200D is designed to support Dolby Sound Room and Dolby Home Theater levels of Dolby’s PC Entertainments Experience logo program. |
