Data and Voice Modems

Data and Voice Modems

ISOmodem Data + Voice chipsets implement a complete PSTN modem and range in speed from 2400 – 56,000 bps. The Si2439/94 offers advanced voice processing in addition to machine to machine communications capabilities, making it easy to add telephony features to any embedded system. The on-chip command processor handles all time-critical tasks and makes them easy to integrate into your system. They all utilize Silicon Labs’ patented direct access arrangement (DAA) technology to implement a globally-compliant telephone line interface with unparalleled integration and proven robustness. A single hardware design can support all speeds and countries with a single bill of materials (BOM).
