The Si2493 ISOmodem is a complete, ITU V.92-compliant, full-featured
modem that provides conventional data formats with connect rates of up to
56,000 bps, full-duplex, over the Public Switched Telephone Network
(PSTN). Offered as a chipset with the Si2493 system-side device and the
Si3018 line-side device, the ISOmodem utilizes Silicon Laboratories’
patented Direct Access Arrangement (DAA) technology to provide a
programmable telephone line interface with an unparalleled level of
integration. This compact solution eliminates the need for a separate DSP,
modem controller, codec, transformer, relay, opto-isolators, clocking
crystal, and 2–4 wire hybrid. Available with a system-side packaging option
of either a 16-pin SOIC or a 24-pin TSSOP, the Si2493 is ideal for
embedded modem applications due to its flexibility, small footprint, and
minimal external component count.
