GENERAL DESCRIPTION
STw5093 is a high performance low power combined
PCM CODEC/FILTER device tailored to implement the
audio front-end functions required by low voltage/low
power consumption digital cellular terminals. STw5093
offers a number of programmable functions accessed
through a serial control channel that easily interfaces to
any classical microcontroller. The PCM interface sup-
ports both non-delayed (normal and reverse) and de-
layed frame synchronization modes.
STw5093 can be configurated either as a 14-bit lin-
ear or as an 8-bit companded PCM coder.
Additionally to the CODEC/FILTER function, STw5093
includes a Tone/Ring/DTMF generator, a sidetone gen-
eration, and a buzzer driver output.STw5093 fulfills and
exceeds D3/D4 and CCITT recommendations and ETSI
requirements for digital handset terminals.
Main applications include digital mobile phones, as
cellular and cordless phones, or any battery powered
equipment that requires audio codecs operating at
low single supply voltages.
1.8V TO 3.3V CMOS COMPATIBLE DIGITAL
INTERFACES.
PROGRAMMABLE PCM AND CONTROL
INTERFACE MICROWIRE COMPATIBLE.
GSM/DCS1800/PCS1900/JDC DIGITAL
CELLULAR TELEPHONES.
CDMA CELLULAR TELEPHONES.
