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.
