DESCRIPTION
IDT's STAC9758/9759 are general purpose 20-bit, full duplex, 6-Channel audio CODECs conforming to the analog component specification of AC '97 (Audio Codec 97 Component Specification Rev. 2.3). Packaged in an AC '97 compliant 48-pin TQFP, the STAC9758/9759 can be placed on the motherboard, daughter boards, PCI, AMR, CNR, MDC or ACR cards. Supported ADC and DAC audio sample rates include 96kHz, 48kHz, 44.1kHz, 32kHz, 22.05kHz, 16kHz, 11.025kHz, and 8 kHz; additional rates are supported in the STAC9758/9759 soft audio drivers. All ADCs and DACs operate at 20-bit resolution. SPDIF_OUT supported sample rates include 96kHz, 48kHz, 44.1kHz and 32kHz. SPDIF_IN supports 48kHz and 44.1kHz. The STAC9758/9759 includes internal jack sensing using proprietary IDT current and impedance-sensing techniques. The impedance load on any of the inputs or outputs can be detected. The STAC9758/9759 also supports Universal JacksTM functionality for jack interchangeability. The GPIOs on the STAC9758/9759 remain available for advanced configurations.
