Its characteristics and specifications are subject to change without notice. Si2401 V.22BIS ISOMODEM® WITH INTEGRATED GLOBAL DAA Features Applications Description 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, opto- isolators, and 2–4 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.
