Features
Applications
Description
The Si2494/39 ISOmodem is a full-featured ITU V.92/V.34-compliant modem that
provides connect rates of up to 56 kbps, full-duplex, over the public switched
telephone network (PSTN). Offered as a chipset with the Si2494/39 system-side
device and the Si3018 line-side device, the ISOModem utilizes Silicon
Laboratories’ patented direct access arrangment (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. The
addition of the Si3000 voice codec supports a voice handset and/or full-duplex
speakerphone. Voice pass-through with optional compression supports tapeless
answering machine, music-on-hold, voice menus, etc. The Si2494/39 is ideal for
embedded modem applications due to its flexibility, small footprint, and minimal
external component count.
