GENERAL DESCRIPTION
STw5094A is a low power asynchronous stereo
audio DAC device with headphones amplifiers for
high quality MP3 and FM radio listening. The
STw5094A includes also an high performance
low power combined PCM Codec
filter tailored to
implement the audio front-end functions required
by low voltage low power consumption digital cel-
lular terminals with added MP3 and FM radio lis-
tening.
The STw5094A registers are accessed through an
I2C-bus compatible interface.
The STw5094A asynchronous stereo audio DAC
section is suited for MP3, or any other audio stereo
source, listening. It supports any rate from 8 kHz
to 48 kHz, can tolerate jitter on audio data and
does not requires an oversampled clock. The au-
dio data serial interface can be master or slave, it
is I2S compatible and supports other standard se-
rial interface formats. The internal D to A convert-
ers work with 18 bit input resolution.
The stereo headphones drivers can also be used
for FM radio listening via an auxiliary stereo ana-
log input. A loudspeaker driver can also be used
for monophonic group listening.
The STw5094A voice Codec section can be con-
figured either as a 14-bit linear or as an 8-bit com-
panded PCM coder. The frame voice Codec
sample rate can be either the standard 8 kHz val-
ue or the extended 16 kHz one.
In addition to the stereo audio DAC and Codec
fil-
ter
functions,
STw5094A
includes
a
tone
ring DTMF generator that can be used both
in audio listening mode and in voice Codec mode,
a sidetone generation, a buzzer driver output and
a remote control function tailored to handle an ex-
ternal on-hook off-hook button. STw5094A Voice
Codec fulfills and exceeds D3
D4 and CCITT
recommendations and ETSI requirements for dig-
ital handset terminals. The Stereo Audio DAC part
fulfills and exceeds the requirements for MP3
quality and FM radio quality listening. Main appli-
cations include digital mobile phones with added
low-power high-quality MP3 and
or FM radio lis-
tening features, or any battery powered equipment
that requires Stereo Audio DAC with Headphones
drivers.
