2-CHANNEL HIGH DEFINITION AUDIO CODEC

PC AUDIO

1. DESCRIPTION

The 92HD001 is a high quality, 2-channel audio CODEC compatible with the Intel High Definition (HD) Audio

Interface. The 92HD001 provides high quality, HD Audio capability to notebook and cost sensitive desktop PC

applications.

The 92HD001 incorporates IDT's proprietary 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 note-

book, desktop and media center PCs.

The 92HD001 provides Stereo 24-Bit, full duplex resolution supporting sample rates up to 192 KHz by the DAC

and ADC. The 92HD001 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 supports all desired two channel configurations, including switchable Headphone Out, and Uni-

versal 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 92HD001

has four General Purpose I/O (GPIO) pins. The 92HD001 also provides a single ended CD input to avoid DRM

incompatibility and to support legacy OS issues.

The 92HD001 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 92HD001 operates with a 3.3V digital supply and is available in either 5V or 3.3V analog supply.

The 92HD001 is available in 48-pin LQFP RoHS package.

The 92HD001 is supported with IDT’s high quality software solutions which include drivers for all major Win-

dows 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 tech-

nologies like SRS WOW®, Knowles® Microphone Beam forming, Waves MaxxBASS® and more.
