Product Summary
The SI2401-FS ISOmodem is a complete, two-chip, 2400 bps modem integrating Silicon Laboratories fourth-generation direct access arrangement (DAA), which provides a globally-programmable telephone line interface with an unprecedented level of integration. Available in two small packages, this compact solution eliminates the need for a separate DSP data pump, modem controller, codec, isolation transformer, relay, opto-isolators, and 2-4 wire hybrid. The SI2401-FS provides conventional data formats at connect rates of up to 2400 bps with full-duplex operation over the Public Switched Telephone Network (PSTN). The SI2401-FS is ideal for embedded modem applications due to its small size, minimal external component count, and low power consumption.
