ISOmodem chipsets implement a complete PSTN modem and range in speed from 2400 – 56,000 bps. The on-chip command processor handles all time-critical tasks and makes them easy to integrate into your system. They all utilize Silicon Labs’ patented direct access arrangement (DAA) technology to implement a globally-compliant telephone line interface with unparalleled integration and proven robustness. A single hardware design can support all speeds and countries with a single bill of materials (BOM). The ISOmodem family of compact solutions eliminate the need for a separate DSP, modem controller, codec, transformer, relay, opto-isolators and 2-4 wire hybrid. These modems are ideal for embedded data applications due to their flexibility, small footprint and minimal external components.
