Description

Si2403

CLKIN/XTALI

EECLK/D5

The Si2403 is a complete, ITU-V.22bis-compliant, 2400 bps 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-

wire hybrid. The ISOmodem® chipset is ideal for embedded modem

applications due to its small board space, low power consumption, and

global compliance.
