DESCRIPTION (CONTINUED)
The STAC9766/67 block diagram is illustrated on page 3. It provides variable sam-
ple rate Digital-to-Analog (DA) and Analog-to-Digital (AD) conversion, mixing, and
analog processing. Supported audio sample rates include 48 kHz, 44.1 kHz,
32 kHz, 22.05 kHz, 16 kHz, 11.025 kHz, and 8 kHz; additional rates are supported
in the STAC9766/67 soft audio drivers. The digital interface communicates with the
AC
’
97 controller via the five-wire AC-Link and contains the 64-word by 16-bit regis-
ters. The two DACs convert the digital stereo PCM-out content to audio. The MIXER
block combines the PCM_OUT with any analog sources, to drive the LINE_OUT
and HP_OUT outputs. The MONO_OUT delivers either mic only, or a mono mix of
sources from the MIXER. The stereo variable sample rate ADC
’
s provide record
capability for any mix of mono or stereo sources, and deliver a digital stereo PCM-in
signal back to the AC-Link. The microphone input and mono input can be recorded
simultaneously, thus allowing for an all digital output in support of the digital ready
initiative. All ADC
’
s operate at 18-bit resolution and DAC
’
s at 20-bit resolution. For a
digital ready record path, the microphone is connected to the left channel ADC while
the mono output of the stereo mixer is connected to right channel ADC. Make sure
the microphone input is not connected to the stereo mixer when in this mode.
The STAC9766/67 supports General Purpose Input/Output (GPIO), as well as
SPDIF output. These digital I/O options provide for a number of advance architec-
tural implementations, with volume controls and digital mixing capabilities built
directly into the codec.
The STAC9766/67 is designed primarily to support stereo (2-speaker) audio. True
AC-3 playback can be achieved for 6-speaker applications by taking advantage of
the multi-codec option available in the STAC9766/67 to support multiple codecs in
an AC'97 architecture. Additionally, the STAC9766/67 provides for a stereo
enhancement feature, SigmaTel Surround 3D (SS3D). SS3D provides the listener
with several options for improved speaker separation beyond the normal 2/4-
speaker arrangements.
Together with the logic component (controller or advanced core logic chip-set) of
AC'97, STAC9766/67 can be SoundBlaster
and Windows Sound System
compat-
ible with SigmaTel
