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.
