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.
