The Si2456 is a complete, ITU-V.90-compliant, 56 kbps modem chipset  
with integrated direct access arrangement (DAA) that provides a  
programmable line interface to meet global telephone line requirements  
with a single design. 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.
