92hd001/92hd001d v 1.0 12/06 idt confidential 1. description the 92hd001/92hd001d is a high quality, 2-channel au dio codec compatible with the intel high definition (hd) audio interface. the 92hd001/92hd001d provides high quality, hd audio capability to notebook and cost sensitive desktop pc applications. the 92hd001/92hd001d incorporates idt's proprietar y sd technology to achieve a dac snr in excess of 95db. the higher performance and quality of idt?s audio solutions brings consumer device level performance to the notebook, desktop and media center pcs. the 92hd001/92hd001d provides stereo 24-bit, full duplex resolution supporting sample rates up to 192 khz by the dac and adc. the 92hd001/92hd001d 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 92hd001/92hd001d supports all desired two ch annel configurations, including switchable headphone out, and universal jacks tm functionality for automatic jack detection sensing and retasking. the spdif inter- face provides connectivity to consumer electronic eq uipment 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 92hd001/92hd001d has four general purpose i/o (gpio) pins. the 92hd001/92hd001d also provides a single ended cd input to avoid drm incompatibility and to support legacy os issues. the 92hd001/92hd001d integrates a headphone amplifier which is available on ports a and d. the head- phone 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 det ect 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 92hd001/92hd001d operates with a 3.3v digital supply and is available in either 5v or 3.3v analog sup- ply. the 92hd001/92hd001d is available in 48-pin lqfp rohs package. the 92hd001/92hd001d is supported with idt?s high qu ality software solutions which include drivers for all major windows operating systems from microsoft para metric softeq, and digital rights management. third party plugin capability is easily achieved with the idt ke rnel 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 92hd001d is designed to support dolby sound room and dolby home theater levels of dolby?s pc entertainments experience logo program. 92hd001/92hd001d 2-channel high definition
