Description

The Si2400 ISOmodem™ is a complete modem chipset with integrated

direct access arrangement (DAA) that provides a programmable line

interface to meet global telephone line requirements. Available in two 16-

pin small outline (SOIC) packages, it eliminates the need for a separate

DSP data pump, modem controller, analog front end (AFE), isolation

transformer, relays, opto-isolators, 2- to 4-wire hybrid, and voice codec.

The Si2400 is ideal for embedded modem applications due to its small

board space, low power consumption, and global compliance.
