Description

The ISOmodem

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.
