Si2401

Note: Permanent device damage may occur if the above absolute maximum ratings are exceeded. Functional peration should be restricted to the conditions as specified in the operational sections of this data sheet. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The Si2401 ISOmodem^® is a complete two-chip 2400 bps modem integrating Silicon Labs' third-generation direct access arrangement (DAA), which provides a globally-programmable telephone line interface with an unprecedented level of integration. Available in two 16-pin SOIC packages, this compact solution eliminates the need for a separate DSP data pump, modem controller, codec, isolation transformer, relay, optoisolators, and 24 wire hybrid. The Si2401 provides conventional data formats at connect rates of up to 2400 bps, with full-duplex operation over the Public Switched Telephone Network (PSTN). Additionally, the Si2401 is fully-programmable to meet global standards with a single design. Other features include fast connect times for electronic point-of-sale (EPOS) applications and alarm protocols for security systems. The device is ideal for embedded modem applications due to its small size, low external component count, and low power consumption.
