Description

The Si2436-FT is a model of electronic component in the IC Chips category. It is a complete, two-chip, 2400 bps modem integrating Silicon Laboratories’ fourth-generation direct access arrangement (DAA). This modem provides a globally-programmable telephone line interface with an unprecedented level of integration. The Si2436-FT is available in two small packages, eliminating the need for a separate DSP data pump, modem controller, codec, isolation transformer, relay, opto-isolators, and 2–4 wire hybrid. It supports conventional data formats at connect rates of up to 2400 bps with full-duplex operation over the Public Switched Telephone Network (PSTN). This electronic component is ideal for embedded modem applications due to its small size, minimal external component count, and low power consumption.
