Offered as a chipset with the Si2457, Si2434, Si2415, or Si2404 system-side device and the Si3018/10 line-side device, the ISOmodem utilizes Skyworks Solutions’ patented direct access arrangement (DAA) technology to provide a programmable telephone line interface with an unparalleled level of integration.
These compact solutions eliminate 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, these devices are ideal for embedded modem applications due to their flexibility, small footprint, and minimal external component count.
