Available in two small packages, it eliminates the need for a separate DSP data pump, external RAM and ROM, modem controller, analog front end (AFE), isolation transformer, relays, opto- isolators, and 2- to 4-wire hybrid. The ISOmodem™ is ideal for embedded modem applications due to its small board space, low power consumption, and global compliance. The Si2433 and Si2414 products offer all the same features as the Si2456 with connect rates of up to 33.6 kbps and 14.4 kbps, respectively.
