The ISOmodem family of products are complete modems ranging in speed from 2400 bps to

DESCRIPTION

56,000 bps. Offered as a chipset with a 16-pin global line side device, the ISOmodem utilizes

Silicon Laboratories’ patented direct access arrangement (DAA) technology to provide a

programmable telephone line interface with an unparalleled level of integration. The universal

design can support all speeds and countries with a single Bill of Materials (BOM). These compact

solutions eliminate the need for a separate DSP, modem controller, codec, transformer, relay,

opto-isolators, clocking crystal and 2-4 wire hybrid. These devices are ideal for embedded data

modem and data/voice modem applications due to their flexibility, small footprint, and minimal

external components.
