Description The STAC9220/9221/9223 are high fidelity, 8-channel audio CODECs compatible with the Intel High Definition (HD) Audio Interface. The STAC9220/9221/9223 provide high quality, HD Audio capability to notebook and cost sensitive desktop PC applications. The STAC9221 CODEC incorporate IDT's proprietary Σ∆ technology to achieve an estimated DAC SNR in excess of 105dB. The STAC9220/9223 CODEC incorporates IDT's proprietary Σ∆ technology to achieve an estimated DAC SNR in excess of 95dB. The STAC9223 has all of the features of the STAC9220 plus ADAT Optical “Lightpipe.” The higher performance and quality of IDT’s audio solutions brings consumer electronics level performance to the notebook, desktop and media center PC. The STAC9220/9221/9223 provide stereo 24-bit, full duplex resolution supporting sample rates up to 192 KHz by the DAC and ADC. The STAC9220/9221/9223 DAC, ADC and SPDIF In/Out support sample rates of 96 KHz, 48 KHz and 44.1 KHz. Additional sample rates are supported by the driver software. The STAC9220/9221/9223 support all desired eight channel configurations, including switchable Headphone Out, and Universal Jacks™ 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. IDT™ 8-CHANNEL HIGH DEFINITION AUDIO CODEC 12 STAC9220/9221/9223 V 0.96 102706 STAC9220/9221/9223 8-CHANNEL HIGH DEFINITION AUDIO CODEC PC AUDIO MIC inputs can be programmed with 0/10/20/30/40dB boost. For more advanced configurations, the STAC9220/9221/9223 have three General Purpose I/O (GPIO) pins. The STAC920/9221/9223 also provide a single ended CD input for compatibility with DRM solutions and to support legacy OS issues. The STAC9220/9221/9223 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. An additional headphone is supported on Port F. 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 IDT 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 IDT STAC922x reference design for circuit implementation details. The STAC9220/9221/9223 operates with a 3.3 V digital supply and is available in either 5 V analog supply or 3.3 V analog supply options. The STAC9220/9221/9223 are available in a 48-pin LQFP package. The 48-pin LQFP is only available in the Environmental package (Pb-free).

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 and F. Refer to the reference design for port detect circuitry. Select the precision of the resistor used as follows. Table 4. Audio Jack Presence Detect 4.2.

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. 4.3. SPDIF Output SPDIF Output can operate at 44.1 KHz, 48 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.

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: Headphone capabilities are provided on pins 39/41 and 35/36, but one should not put headphone loads on both sets of pins at the same time. Note3: 40dB Microphone boost is not recommended.

The HD Audio spec states that the beep tone frequency: F = (48 KHz HD Audio SYNC rate) / (4*Divider) producing tones from 47 Hz to 12 KHz (logarithmic scale). This part generates tones with frequency: F = 48000 * (257 - Divider) / 1024 yielding a linear range from 12 KHz to 93.75 Hz in steps of 46.875 Hz. If JackSenseVSR[Rate2x], then the beep tones generated have frequency: F = 48000 * (513 - Divider) / 1024 yielding a range of 24 KHz to 12093.75 Hz in steps of 46.875 Hz. 6.25.
