1. DESCRIPTION
The STAC927x (STAC9271/9272/9273/9274) family are high fidelity, 10-channel audio CODECs compatible with the Intel High Definition (HD) Audio Interface (formerly known as "Azalia"). The STAC927x family of CODECs provides high quality, HD Audio capability to notebook and cost sensitive desktop PC applications. The STAC927x family incorporates 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 STAC927x family provides 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 STAC927x family supports 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 STAC927x family has up to five General Purpose I/O (GPIO) pins. The STAC927x family also provides a single ended CD input for compatibility with DRM solutions and to support legacy OS issues. The STAC927x family 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 IDT STAC927x reference design for circuit implementation details. The STAC927x family operates with a 3.3 V digital supply and a 3.3 V to 5 V analog supply. The STAC927x family is available in a 48-pin LQFP Environmental (ROHS) packages.

3. DETAILED DESCRIPTION 3.1. Universal JacksTM
IDT's Universal JacksTM technology allows for the greatest flexibility in board design and implementation. For the STAC927x family the Universal JacksTM capabilities are as follows1: * Ports A, B, and D support2: * Headphone Out * Line Out * Line In * Mic with 0/10/20/30/40 dB Mic boost3 Ports C, E, F, G, H support2: * Line Out * Line In * Mic with 0/10/20/30/40 dB Mic boost3 * Ports G & H do not have VrefOut Support
*
Note1: On the STAC927x family, only one function can be selected on each pin pair at a time. 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.

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. Refer to the reference design for port detect circuitry. Select the precision of the resistors used as follows:

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 output drivers. Please reference the HD Audio Universal Jack Application Note on the IDT Extranet for more information.

SPDIF Input
SPDIF IN can operate at 44.1 KHz, 48 KHz or 96 KHz and implements internal Jack Detect. 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.

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
ADAT(R), or "Lightpipe" is available on all versions of STAC927x family. 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
The digital microphone interface permits connection of a digital microphone(s) to the STAC927x family 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 STAC927x family. 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 STAC927x family supports the digital microphone configurations described in Tables 3 and 4, and shown in Figures 1, 2 and 3, below.

Table 465. ADATOut VCSR0 Command Response Format Bit Bitfield Name RW Reset Description ADAT Sample Split Format Select 1: U user bits U3 and U2 in the transmitted ADAT stream are supplied by bits 3:2 of this verb (field ADAT), under software control. 0: U user bits U3 and U2 in the transmitted ADAT stream are controlled automatically by hardware, derived according to the sample-rate of the outgoing audio stream. Hardware support is provided for the transfer of double- and quad-rate data streams over the 48 KHz (nominal) 8-channel ADAT interface. Two 2-channel (stereo) streams or one 4-channel audio stream at double-rate or one 2-channel stream at quad-rate will be sample-split over the appropriate ADAT channels. For each mode, the ADAT channels are listed in the order of arrival of the corresponding audio sample: ADAT_2CH_SGL C0,C1 (C2-C7 zero padded) ADAT_2CH_DBL C0,C2,C1,C3 (C4-C7 zero padded) ADAT_2CH_QUAD C0,C4,C1,C5,C2,C6,C3,C7 ADAT_4CH_SGL C0,C1,C2,C3 (C4-C7 zero padded) ADAT_4CH_DBL C0,C2,C4,C6,C1,C3,C5,C7 ADAT_8CH_SGL C0,C1,C2,C3,C4,C5,C6,C7 ADAT Lightpipe Control Used in conjunction with the ADAT Sample Rate in the stream converter to generate the 4 bit ADAT control signals. ADAT0 (U0): Time Code FLAG ADAT1 (U1): MIDI FLAG ADAT2 (U2): 0 = 44.1/48 KHz audio (1X operation) 1 = 88.2/96 KHz audio (2X operation) ADAT3 (U3): 1 = 176.4/192 KHz audio (4x operation) User bits U0 and U1 are always under software control. User bits U2 and U3 are also under software control if ADATFRMT is set. If ADATFRMT = 0, then bits 3:2 here are ignored and the bits transmitted as U3:U2 are controlled by hardware according to the sample-rate of the data stream.
