The STAC9250/92511 provide high quality, HD Audio capability to notebook and cost sensitive desktop PC applications. The STAC9250/9251 incorporate IDT's proprietary technology to achieve a DAC SNR of 100dB. The higher performance and quality of IDT’s audio solutions brings consumer electronics level performance to the notebook, desktop and media center PC. The STAC9250/9251 provide stereo 24-bit, full duplex resolution supporting sample rates up to 192 KHz by the DAC and ADC. The STAC9250/9251 SPDIF In/Out support sample rates of 96 KHz, 48 KHz and KHz plus SPDIF_OUT supports KHz. Additional sample rates are supported by the driver software. The STAC9250/9251 supports flexible 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 STAC9250/9251 have four General Purpose I/O GPIO pins. The STAC9250/9251 also provide a single ended CD input for compatibility with DRM solutions and to support legacy OS issues. The STAC9250/9251 integrate 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. The Universal Jack capabilities allow the CODECs to detect when audio devices are connected, and allow the CODECs to be reconfigured to support these devices regardless of which port they are connected to. 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 STAC9250/9251 reference design for circuit implementation details. The STAC9250/9251 operate with a V digital supply and a V, 4 V, and 5 V analog supply. The STAC9250/9251 are available in a 48-pin LQFP Environmental ROHS package.
