DESCRIPTION
SigmaTel’s STAC9766/67 are general purpose
18-bit ADCs and 20-bit DACs, full duplex, audio
codecs conforming to the analog component
specification of AC’97 (Audio Codec 97 Compo-
nent Specification Rev. 2.2). The STAC9766/67
incorporate SigmaTel’s proprietary
Σ
technology
to achieve a DAC SNR in excess of 95 dB. The
DACs, ADCs, and mixer are integrated with ana-
log I/Os, which include four analog line-level ste-
reo inputs, two analog line-level mono inputs, two
stereo outputs, and one mono output channel.
The STAC9766/67 include digital input/output
capability for support of modern PC systems with
an output that supports the SPDIF format. The
STAC9766/67 is a standard 2-channel stereo
codec. With SigmaTel
’
s headphone drive capabil-
ity, headphones can be driven with no external
amplifier. The STAC9766/67 may be used as a
secondary codec, with the STAC9700/21/44/56/
08/84 as the primary, in a multiple codec configu-
ration conforming to the AC'97 Rev. 2.2 specifica-
tion. This configuration can provide true six-
channel, AC-3 playback required for DVD applica-
tions. The STAC9766/67 communicates via the
five-wire AC-Link to any digital component of
AC'97 providing flexibility in the audio system
design. Packaged in an AC'97 compliant 48-pin
TQFP, the STAC9766/67 can be placed on the
motherboard, daughter boards, PCI, AMR, CNR,
or ACR cards.
