1 / 22 page  73M2901CE V.22bis Single Chip Modem Simplifying System Integration™ DATA SHEET DS_2901CE_031 April 2009 Rev. 3.3 © 2009 Teridian Semiconductor Corporation 1 DESCRIPTION The 73M2901CE low speed modem integrates a data pump, controller, and analog front end in a 3.3 V device with a powerful "AT" command host interface. The modem reduces external component count/cost by incorporating many features like parallel phone detect, Line-In-Use and Ring detection in software without requiring additional components. The device is a "one chip fits all” solution for applications including set-top boxes, point-of-sale terminals, automatic teller machines, utility meters, vending machines and smart card readers. Another distinctive feature of this device is pin compatibility with Teridian’s flagship embedded hard modems, the 73M2901CL, and the 73M1903 soft modem AFE. This offers customers a cost effective method to design for both hard or soft modem solutions in the same system as a risk-free cost reduction path. Complete support, modem reference designs and error correction software are part of the solution offered by Teridian. Our in-house application engineering team is here to help meet your international certification needs.
