SI2457 General Description
The ISOmodem® family of products is a complete modem ranging in speed from 56,000 bps to 2400 bps. Offered as a chipset with the Si2457,Si2434, Si2415, or Si2404 system-side device and the Si3018/10 lineside 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. 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.
