The ISOmodem® chipsets utilize Silicon Laboratories’ third-generation direct access arrangement (DAA) to provide a globally-programmable telephone line interface with an unparalleled level of integration. By sharing the same line-side device, a single design can be used in all countries and for all modem speeds. Available in two small packages, these compact solutions eliminate the need for a separate DSP, modem controller, codec, isolation transformer, relay, opto-isolators, clocking crystal, and 2–4 wire hybrid. The ISOmodem provides conventional data formats with connect rates of up to 56,000 bps, full-duplex, over the Public Switched Telephone Network (PSTN). These devices are ideal for embedded modem applications due to their flexibility, small footprint, and minimal external component count.
