DESCRIPTION The 92HD001/92HD001D is a high quality, 2-channel audio 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 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 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 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 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 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 92HD001/92HD001D operates with a 3.3V digital supply and is available in either 5V or 3.3V analog supply. The 92HD001/92HD001D is available in 48-pin LQFP RoHS package. The 92HD001/92HD001D 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 Headphone®, 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.

SPDIF Input SPDIF IN can run at 44.1 KHz, 48 KHz and 96 KHz, and has internal Jack Sensing. A sophisticated digital PLL allows automatic rate detection and accurate data recovery. The ability to directly accept consumer SPDIF voltage levels eliminates the need for costly external receiver ICs. Advanced features such as record slot select and SPDIF_IN routing to the DAC allows for simultaneous record and play. 3.2. SPDIF Output SPDIF Output can run at 44.1 KHz, 48 KHz, and 96 KHz at bit rates up to 24 bits, as defined in the Intel High Definition Audio Specification. This insures compatibility with all consumer audio gear and allows for convenient integration into home theater systems and multi-media centers. 3.3. Universal JacksTM IDT’s Universal JacksTM technology allows for the greatest flexibility in board design and implementation. For the 92HD001/92HD001D the Universal JacksTM capabilities are as follows • All of the 92HD001/92HD001D ports support: • Line Out • Line In • Mic with 0/10/20/30/40 dB Mic Boost • Ports A and D also support • Headphone Out1 1 Headphone capabilities are available on pins 39/41 and 35/36, but one should not put headphone loads on both sets of pins at the same time. Note: On the 92HD001/92HD001D only one function can be selected at a time, you cannot have an input and output at the same time on the same set of pins. This function can be changed at any time. 3.4. Audio Jack Presence Detect Sense_A pin is used to detect the presence of plugs in ports A, B, C, and D. Refer to the reference design for port detect circuitry. Select the precision of the resistors used as follows: AVDD Nominal Voltage (+- 5%) Resistor Tolerance (If Port D is used) Resistor Tolerance (If Port D is not used) 5V 1% 1% 4.5V 1% 1% 4V 0.50% 1% 3.3V 0.10% 1% Includes pull-up resistors on Sense A and series resistors between jack switch and Sense A.
