Description
The ISOmodem family of products is a complete modem ranging in speed
from 56,000 bps to 2400 bps. Offered as a chipset with the Si2457, Si2434,
Si2415, or Si2404 system-side device and the Si3018/10 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. These compact solutions
eliminate the need for a separate DSP, modem controller, codec,
transformer, relay, opto-isolators, clocking crystal, and 2-4 wire hybrid.
Available with a system-side packaging option of either a 16-pin SOIC or a
24-pin TSSOP, these devices are ideal for embedded modem applications
due to their flexibility, small footprint, and minimal external component
count.
