DESCRIPTION The STAC9271/74 are 10-channel audio CODECs compatible with the Intel High Definition (HD) Audio Interface (formerly known as "Azalia"). The STAC9271/74 CODECs provide high quality, HD Audio capability to notebook and cost sensitive desktop PC applications. The STAC9271/74 incorporate IDT's proprietary technology to achieve a DAC SNR up to 105dB. The higher performance and quality of IDT's audio solutions brings consumer electronics level performance to the notebook, desktop and media center PC. The STAC9271/74 provide stereo 24- bit, full duplex resolution, supporting sample rates up to 192 KHz by the DAC and ADC. The SPDIF In/Out support sample rates of 96 KHz KHz, 48 KHz and 44.1 KHz plus SPDIF OUT supports 88.2 KHz. Additional sample rates are supported by the driver software. The STAC9271/74 support all desired ten channel configurations, including switchable Headphone Out, and Universal JacksTM functionality for jack detection and re-tasking. The SPDIF interface provides connectivity to Consumer Electronic equipment like Dolby Digital decoders, powered speakers, mini disk drives or a home entertainment systems. 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 STAC9271/74 have up to five General Purpose I/O (GPIO) pins. Also provides a single ended CD input for compatibility with DRM solutions and to support legacy OS issues. STAC9271/74 integrates a headphone amplifiers on Ports A, B and D. The headphone amplifier is dedicated to these three outputs for increased flexibility, enhanced user experience, and reduced implementation costs. The Universal JackTM feature allows the CODECs to detect when audio devices are plugged in, and for the CODECs to be reconfigured to support these devices regardless of which port they are plugged into. SPDIF input sensing is also supported. The fully parametric IDT SoftEQ can be initiated/disabled upon headphone jack insertion/removal for protection of notebook speakers. Note: The Jack Detect circuit and component selection are critical for accurate detection of audio jacks on individual ports. Please see the reference design for circuit implementation details. The STAC9271/74 can operate with a 3.3 V digital supply and a 5 V analog supply. The STAC9271/74 are available in a 48-pin LQFP Environmental (ROHS) packages.

For example, a pin pair cannot be configured as an input and output at the same time. Configuration can be changed at any time. Note2: Three Headphones should not be used simultaneously. Performance degradation will occur when using 2 Headphones simultaneously. See electrical specs for details. Note3: When the 40dB mic boost feature is enabled, additional gain increases greater than 6dB may result in significant audio quality degradation of the microphone audio input. In particular, when the 40dB MIC boost is active, the SNR, THD+N and DC offset will significantly degrade regardless of the input signal level. 3.1.1. Audio Jack Presence Detect SENSE_A pin is used to detect the presence of plugs in ports A, B, C, and D. SENSE_B pin is used to detect the presence of plugs in ports E, F, G, ad H.

Impedance Sense Impedance Sense is accomplished by on-chip circuitry that measures the impedance at the pin of the chip and compares it to internal reference impedance. Below is a table that contains the bin information and codes returned when the pin widget impedance field in the Port Pin Sense widget is read. Please note that even under the best conditions, there is no method to guarantee 100% impedance sensing due to variations in external circuitry and impedance overlap of devices that can be plugged into a jack. The impedance sense table reflects both standard Line Out and Headphone IDTTM 10-CHANNEL HIGH DEFINITION AUDIO CODEC 26 IDT CONFIDENTIAL STAC9271/9274 V 1.1 01/08 STAC9271/9274 10-CHANNEL HIGH DEFINITION AUDIO CODEC PC AUDIO output drivers.

A sophisticated digital PLL allows automatic rate detection and accurate data recovery. The ability to accept consumer SPDIF voltage levels directly 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.

PC AUDIO SPDIF Output SPDIF Ouput can operate at 44.1 KHz, 48 KHz, 88.2 KHz and 96 KHz, as defined in the Intel High Definition Audio Specification, with resolutions up to 24 bits. This insures compatibility with all consumer audio gear and allows for convenient integration into home theater systems and media center PCs. 3.4. ADAT(R) Output (STAC9274) ADAT(R), or "Lightpipe" is available on the STAC9274. ADAT(R) is a single bit stream optical digital interface for up to 8 channels of uncompressed 24-bit data. Sample rates up to 192 KHz are supported for 2 channels, up to 96 KHz for 4 channels, or up to 48 KHz for 8 channels. 3.5. Digital Microphone Support (STAC9274) The digital microphone interface permits connection of a digital microphone(s) to the STAC9274 via the DMIC0, DMIC1, and DMIC_CLK 3-pin interface. The DMIC0 and DMIC1 signals are inputs that carry individual channels of digital Mic data to the codec. In the event that a single microphone is used, the data is routed to both ADC channels. The DMIC_CLK output is programmable from 1.176 MHz to 4.704 MHz in 1.176 MHz increments and is synchronous to the 24 MHz internal clock. The default frequency is 2.352 MHz. Note: Some Digital Microphone implementations support data on either edge, therefore, an external mux may not be required. The STAC9274 supports the digital microphone configurations described in Tables 3 and 4, and shown in Figures 1, 2 and 3, below.
