SKYWORKS SI2435-F-FTR

The Si2435 and Si2417 are complete two-chip fax modems ranging in speed from 33,600 bps to 14,400 bps. The ISOmodem chipsets utilize Silicon Laboratories’ third-generation direct access arrangement (DAA) to provide a globally-programmable telephone line interface with an unparalleled level of integration. Available in two small packages, the compact solutions eliminate the need for a separate DSP, modem controller, codec, isolation transformer, relay, opto-isolators, and 2 4 wire hybrid. The ISOmodem provides conventional fax formats with connect rates of up to 33,600 bps over the Public Switched Telephone Network (PSTN). The Si2435 and Si2417 are ideal for fax modem applications due to their global compliance, small footprint, and minimal external component count.
