DESCRIPTION The STAC9227/9228/9228D are high fidelity, 8-channel audio CODECs compatible with the Intel High Definition (HD) Audio Interface. The STAC9227/9228/9228D CODECs provide high quality, HD Audio capability to notebook and cost sensitive desktop PC applications. The STAC9227/9228/9228D incorporate SigmaTel's proprietary technology to achieve a DAC SNR in excess of 100 dB. The higher performance and quality of SigmaTel's audio solutions brings consumer electronics level performance to the notebook, desktop and media center PC. The STAC9227/9228/9228D provide stereo 24-bit, full duplex resolution supporting sample rates up to 192 KHz by the DAC and ADC. The STAC9227/9228/9228D SPDIF In/Out support sample rates of 96 KHz, 48 KHz and 44.1 KHz plus SPDIF OUT supports 88.2 KHz. Additional sample rates are supported by the driver software. The STAC9227/9228/9228D support all desired eight 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 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 STAC9227/9228/9228D has up to four General Purpose I/O (GPIO) pin. The STAC9227/9228/ 9228D also provide a single ended CD input for compatibility with DRM solutions and to support legacy OS issues. The STAC9227/9228/9228D integrate a headphone amplifier which is available 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 Jack capabilities allow the CODECs to detect when audio devices are connected to the CODEC, and to allow the CODECs to be reconfigured to support these devices regardless of which port they are plugged into the system. SPDIF input sensing is also supported. The fully parametric SigmaTel SoftEQ can be initiated upon headphone jack insertion and 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 STAC9227/9228/9228D operate with a 3.3 V digital supply and a 3.3 V to 5 V analog supply. The STAC9227/9228/9228D are available in a 48-pin LQFP Environmental (ROHS) package.

DETAILED DESCRIPTION 3.1. Universal JacksTM SigmaTel's Universal JacksTM technology allows for the greatest flexibility in board design and implementation. For the STAC9227/9228/9228D family the Universal JacksTM capabilities are as follows1: * Ports A, B, and D support2: * Headphone Out * Line Out * Line In * Microphone with 0/10/20/30/40 dB Microphone boost3: * Ports C, E, F, G, H support2: * Line Out * Line In * Microphone with 0/10/20/30/40 dB Microphone boost3: * Ports G & H do not have VrefOut Support Note1: On the STAC9227/9228/9228D 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 two Headphones simultaneously. See electrical specifications for details. Note3: When the 40dB microphone boost feature is enabled, 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. Refer to the reference design for port detect circuitry.

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

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. 3.4. 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. 3.5. Digital Microphone Support (STAC9228X/D) The digital microphone interface permits connection of a digital microphone(s) to the STAC9228 via the DMIC0, DMIC1, and DMIC_CLK 3-pin interface. The DMIC0 and DMIC1 signals are inputs that IDTTM 8-CHANNEL HIGH DEFINITION AUDIO CODEC 29 IDT CONFIDENTIAL STAC9227/9228/9228D V 1.1 01/08 STAC9227/9228/9228D 8-CHANNEL HIGH DEFINITION AUDIO CODEC PC AUDIO carry individual channels of digital microphone 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. The STAC927x family supports the following digital microphone configurations: Table 2.
