The STAC9220 provides high quality, HD Audio capability to notebook and cost sensitive desktop PC applications. The STAC9220 provides stereo 24-bit, full duplex resolution supporting sample rates up to 192 KHz by the DAC and ADC. The STAC9220 DAC, ADC and SPDIF In/Out support sample rates of 96 KHz, 48 KHz and KHz. Additional sample rates are supported by the driver software. The STAC9220 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. MIC inputs can be programmed with 0/10/20/30/40dB boost. For more advanced configurations, the STAC9220 has three General Purpose I/O GPIO pins. The STAC920 also provides a single ended CD input for compatibility with DRM solutions and to support legacy OS issues. The STAC9220 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 CODEC to detect when audio devices are connected to the CODEC, and to allow the CODEC 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.
