Description

CLKIN/XTALI

EECLK/D5

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, codec, isolation transformer, relays, opto-isolators, and 2- to 4-

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.
