Description IDT's STAC9766/9767 (Revision CC1 and beyond) are general purpose 20-bit, full duplex, audio CODECs conforming to the analog component specification of AC'97 (Audio CODEC 97 Component Specification Rev. 2.3). The STAC9766/9767 incorporates IDT's proprietary Σ∆ technology to achieve a DAC SNR in excess of 103dB. The DACs, ADCs and mixer are integrated with analog I/Os, which include four analog line-level stereo inputs, two analog line-level mono inputs, two stereo outputs, and one mono output channel. The STAC9766/9767 includes digital output capability for support of modern PC systems with an output that supports the SPDIF format. The STAC9766/9767 is a standard 2-channel stereo CODEC. With IDT’s headphone drive capability, headphones can be driven without an external amplifier. The STAC9766/9767 may be used as a secondary CODEC, with the STAC9700/21/44/56/08/84/50/66 as the primary, in a multiple CODEC configuration con- forming to the AC'97 Rev. 2.3 specification. This configuration can provide the true six-channel, AC-3 playback required for DVD applications. The STAC9766/9767 communicates via the five-wire |
