GENERAL DESCRIPTION
STw5094 is a low power Stereo Audio DAC device
with Headphones Amplifiers for high quality MP3 and
FM radio listening. The STw5094 includes also an
high performance
low power
CODEC
FILTER tailored to implement the audio
front-end
functions
required
low power consumption digital cellular terminals with
added MP3 and FM radio listening.
STw5094 offers a number of programmable functions
accessed through an I
2
C-bus compatible interface.
The STw5094 Stereo Audio DAC section is suited for
MP3, or any other audio stereo source, listening. It
supports all the MP3 rates from 8kHz to 48kHz. The
audio data serial interface is I
2
S compatible and can
be programmed to handle 16 to 24 bit word length in-
put data. The internal D to A converters work with 18
bit input resolution.

by
low voltage
The Stereo Headphones drivers can also be used for
FM Radio listening via an auxiliary stereo analog in-
put. A Loudspeaker driver can also be used for mono-
phonic group listening.
The STw5094 Voice Codec section can be configured
either as a 14-bit linear or as an 8-bit companded
PCM coder. The Frame Synchronism frequency of
the Voice Codec can be either the standard 8kHz val-
ue or the extended 16kHz one.
In addition to the Stereo Audio DAC and
CODEC
FILTER functions, STw5094 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 re-
mote control function tailored to handle an external
on-hook off-hook button.
STw5094 Voice Codec fulfills and exceeds D3
D4
and CCITT recommendations and ETSI requirements
for digital handset terminals. The Stereo Audio DAC
part fulfills and exceeds the requirements for MP3
quality and FM radio quality listening. Main applica-
tions include digital mobile phones, as cellular and
cordless phones, with added low-power high-quality
MP3 and
or FM radio listening features, or any bat-
tery powered equipment that requires Stereo Audio
DAC with Headphones drivers operating at low single
supply voltage.
